I remember reading a WoW preview back in 2003, where they described Rogues are the ultimate melee damage dealer, and thinking to myself "That's actually really brilliant, and would be great in D&D. Fighters are defensive, and Rogues are offensive." Doing a little digging, it looks Everquest rogues are also dedicated damage dealers, and that would date back to 1999.
If PF2 finally brought that to DnDish games, that'd be excellent yes.
To be fair, 3.5/PF already did that, to a fair extent - the Rogue's contribution in combat, when he can make one at all, is high, spikey, situational DPR; the Fighter's best contribution, when he can manage it, is blocking a choke-point until the right spell can be cast to end the encounter. 4e continued in that vein and did it better, and balanced the classes into the bargain...
This has been a hallmark of 4E since it was released in 2008. Fighters are defenders with high AC and the ability to punish those enemies who ignore them to attack their allies. And rogues are strikers, with low AC and high damage output.
Yeah, and 4e caught flack for "Being an MMO." While 3.5 caught flack for not doing it well /enough/ especially on the Fighter side ("Fighter SUX!!" "Fighter needs Aggro!").
5e has both the fighter & rogue (& barbarian & almost everyone, really, if they want to) doing solid DPR, and the fighter is tanky enough, so that's not too far off, either - and it catches no flack for it, at all, having threaded the needle between acceptable & accessible.
So, if PF2 wants to go there and make the fighter the Tank and the rogue the DPS, it'll have to thread that needle, too.
It's tough out there for a Game Designer.
