Your heavy bolter is free. I paid 40k for my shuriken cannon, and 40k again for my plasma deffgun. As a shoota/avenger, you've to contend with shield bros, jump packs with area stun, powerfist one hit kill spam, and that's if you survive the long-range awesomeness that is the modded bolter or the heavy bolter.
You find that the cannon is cheese? The only option the eldar has for firing at vehicles or turrets at a distance? As a Havoc, it's a dream come true to have the lascannon available. Even the orkz have the zzapgun. Naturally, the shuriken cannon is the second best heavy weapon in the game, no doubt. Behind the heavy bolter, of course. If you're implying that you yourself pick the absolute worst weapons available for your games, then in your view, yes I would be "cheesing". But I don't see any melee marines running around at level 5 with chainswords by choice.
No clue, I always figured the first numbers were Damage, the second was Durability Damage, though I've never looked into it, and I'm probably wrong. That being said, I've done some testing on Power Attacks. The Banshee Power Attack is the same speed-ish as a Combat Knife Power attack. But, Power Attacks for all "Swords", chain and power, for all factions, are incredibly fast. They all take effectively the same time to Power Attack as a Combat Knife. Which is kind of bullshit, but that's a different discussion. As for the Banshee, while her Power Attack is just as fast as one using a Combat Knife, that isn't much difference from the other factions. What creates the problem is really the same problem I've had with the Eldar thus far. She's faster than marines, with a smaller hitbox, and is plenty durable. On top of that she has her scream, which...well for all argument's sake is really not a point for or against her, it's still kind of off. So, after some personal testing and thought, I'm reformulating my opinion to... 1.) Power Attacks from "Heavier" weapons shouldn't be as fast as a Combat Knife, and definitely not faster. This is for all factions. To be fair, I think they did this to help melee, which would be....ok....if melee wasn't so broken as it is, which of course screws range classes more than melee, when in melee. This is breaking the RPS. 2.) Banshee on her own isn't a problem, her Power Attacks just surprised me as I hadn't tried other faction's melee (or my own) since the Patch very much. 3.) Biggest Problem I have with Eldar (Other than the SC, and of course HB for CSM & LSM), is their durability. They can be effectively just as durable as marines, faster, with a smaller hitbox, and in my opinion wielding better weapons.
This video is everything in a nutshell. You can literally dance around your opponents as eldar while bairly being touched. The mobility is so high and damage is so strong that you roll around constantly killing opponents in 1-2 slices.
I find personally playing as a DA I can deal with a melee class some of the time since I can do good damage with the Skuriken and get away, with a tactical you will just get wrecked, as a tactical you cant put down any eldar melee class before they get to you they are just way to fast and hard to hit, and when they do hit they tend to kill you almost instantly, you also have no way to escape since eldar are way faster. As a tactical you are the only LSM class that can cap and they are terrible in confined spaces where all of the capture points are located making tacticals useless, I dont think DAs have this problem with there weapons and speed.
There is a difference between the "worst" and HB equivalents.And no i dont use the HB i use a LC or melta bomds for av and my bolter for anyone else.(saving for a SB for your kind though).
