Yeah but if you think about it only three of our abilities are even "decent", blind hit and stone man? Pure poop and sluggish respectively, Warrior's got at best like three skill categories actually worth upgrading. I guess stone man works for tanks but blind hit is just fudging garbage, especially with the meta revolving around low health-high expertise, and even IF you had 100 hp (like I did before my stat reset), blind hit is still just poop. heck, power smash is arguably pretty useless in the meta aswell, with it's mp draining making upgrading explosions and poison a hinderance to your own survival unless you sacrifice your stats.
Essentially, when people ask for warrior to get buffed, it doesn't just mean looking at the amount of skills, it means looking at which skills are actually useful with the current playstyle of Elia. Archers are arguably the best class in the game, with their passive skills being extremely useful for grinding, with gunmen being a sharp second since they follow the same formula of actually using the mouse instead of the keyboard to attack, which is the reason the caves are so good for gunmen and archers.
When people ask for a warrior buff they are most likely gonna mention how one of their five skill trees is practically worthless, with this "eye for an eye" playstyle being more of an "eye for an appendix" playstyle instead. Doing more damage helps with nothing if you are also hurting yourself every time you hit an enemy, and it simply does not work in a game where having 100 HP even when reaching level 100 is a sign of bad stat management. Low durability, decent defense, and extremely high expertise is the name of the game, and a skill that acts like the plague whenever you attack just ISN'T a worthwhile skill in the slightest. This is not a case of a niche playstyle, it's a case of a completely counter-intuitive one. Seriously name one warrior who actually likes blind hit, I'd be surprised if it was more than the human population of Neptune.
