I also know what you mean.
sadly.
Tends to happen mostly with sword guys though. The RMB spam, still twiches in those old muscles.

Had plenty of help myself.
*shows scars in the back.

But have you also seen, a sorcerer standing just healing, when the traitor is beeing beat in melee, with no clue how to defend himself?

I have seen such things happen. And frankly, I despise both unskilled behaviours: would it be the stab in the back or the healing clueless-ly.

But well... If banshees are able to fight in melee and win (in the new patch), I don't see why sorcerers won't.

the warp whispers that your force swords, will become force daggers.
And if you caress it, with "force" psychic power, your dagger will grow into a full size sword.

Regarding the AS behaviours...yeah somewhere in between.

Know when to heal. Know when to jump in, and help ( not in the back ).

Congratulations, you have completed this course, and you've stopped the fight.

Well, the discussion was about who will be the squishiest bugger around, imo the Hawk certainly wont.

I managed to do multiple matches where i either dont die at all with the SH vet or just once or twice on the basic ones. Tbh, i find the SH the most survivable class in the game if you play him as a harasser rather then pretending you are a Dire Avenger with a get out of jail card.

Ah the good ol * but my team needs help fighting* If the people you are playing with expect you to fight as a healer they are not doing there job right. As a healer you are supposed to buff and keep them alive. And as a fighter your teammate is supposed to adjust himself the best that they can during the fight so you can keep them alive. If a fighter character is getting mad at a healer for not fighting they have issues. I blame battlefield for this bad mentality. Any other game or mmo healers a just that. helpers with very little armor or weapons. Now all of sudden we want a master class that can heal and fight. Nope thats what all the other classes are for. I understand how feel but I that same time I cant stand people who get mad at healers for not throwing themselves into a fight.

Currently, sure they are quite durable and you have either do be dumb enough like me to die or be caught by surprise by a powerfist.
Have you tried UAT's Hawk? I have, and I can you don't wanted to wait around when someone starts shooting at you. Hell, a Smart bolt pistol can gun down a Hawk even if you miss a few shots (which can only happen when the horizontal spread gets too wide). You die in 2fast attacks, and 6bolter rounds, if there aren't any headshots. Yeah, no. Hawks might be the fastest unit in the game, they don't hurt that much and will die like flies with only utility to blind people with sunrifle (that does crap damage).

I know what you mean.
But the moment you "assume" your team mate to do his job....you are in for a world of hurt!
"speaking of general pugging"

Guy ( damage dealer ), loses the combat with you healing. Healer moves in and kills the aggressor.
Guy says "healer you had one job...."

Healer goes like

I havent tried them on UAT, but it sounds like you just have less room for mistakes. Im not saying they wont be squishy, im just saying the Warlock and Sorcerer will certainly be less survivable then a Hawk.

As for not doing damage, i guess we have different experiences there, i love my Hunters Mark. That thing rocks and is far from a slouch in damage (especially due to its accuracy and the ability to land effective headshots). I recommend trying to get as high as you can on Zedek B point and just enjoy either killing or greatly weakening people while they dont even know whats happening.

That's my weapon of choice too. but if you face a stormbolter or a simple bolter by handled an accurate Space Marine, you might have a bad time, especially on UAT.
I've lost efficiency lately. Call it lag, call it bad fps, call it low resolution, I have plenty of excuses... or I'm just bad at the game for some time now... They do have some damage output, but they still get outgunned by anyone who knows how to use a rifle or a smart bolt pistol.

On UAT, they are less survivable. It takes a skilled hawk to score kills and survive. They are still the units that would die the fastest if they don't react.

Got to play on your own terms, you will rarely win a face to face ranged duel due to how the Hunters Mark suffers from strafing enemies (unless you run into some stationary guy, then its Hunting season). You just gotta use your mobility to its best effect and the sheer ambush potential. Always be on some box, on some ledge, any time you are on the "ground level" where all the wingless classes are you are not using your potential to its max.

Only place where the SH does indeed suffer is very small rooms, but i guess thats fair considering how he can make up for that in the open. Even then being in the backlines with a Sunrifle, while not killing stuff, can contribute to a fight indoors well if you pick your targets (shutting down Heavies for example). Its always funny to get the Best Support reward on a SH with the Sunrifle when there are like 2 Warlocks in the same match.
