A raptor/jp assult with extra fuel doesnt have a problem against most if not all classes at the moment.
And this is an example of gameplay inconsistency. Advancements that change the predictability of players against counter-play will spoil for both players, and for everyone. Predictability makes expectation and counter-play more enjoyable, and overall delivers a more consistent experience. It should not be Advancements that improve gameplay it should be the player's acute decisions; the player-skill (e.g. which melee action to take next?)
After 17th patch I rarelly lost Harkus against CSM as a defender. Now I lose it 9 times from 10. Its pretty serious indicator. MoN raptors leads the zerg, supported by autocannons and sorcerers - thats usual setup. I play huge amount of matches per day since 18, so I have pretty clear view. Those "small" buffs of hp and toughness is just enough for raptor to take his kills and safely get away. And engage again. And its not 1 kill, its like 2-3 per landing. Poison beams does significant dmg per second, reaches from afar. I do not see chaos using stormbolters, heavy bolters, plasma guns, traitor assault at all. Main setup now: MoN Sorc Plasma cannon (usually faithful russians) MoN raptor Autocannon MoN bolter
People never learn how to counter a Build or something but only says OP THIS AND OP THAT when will they learn taking an extra fuel helps more in hit and run { used in fortress } than extra health and toughness { which is negligible for the points it costs }
SB is just one class. And its usually like 4-5 per match at most. More often 2-3 guys who are hard to kill, but who can be kited if wanted too. And yours the whole faction are Nurgles now. See the difference? 3 diehards against 15 diehards. So if you use bolter as traitor, you can attack other 12 and feel joy. Me, with bolter, cant have that pleasure at all.
