I thought this poll is about class design.
Archer design = most ego, or most solo, no party play. Only way to contribute is to get top dps. Without top dps or high dps, your party contribution has failed - no support, heal, link, can’t soak damage, etc. When you enter a party, people have to support you since you can’t support them.
Swordsman design = less ego, high HP, some useful debuffs, some classes have excellent burst. Contributes through soaking damage, dps, debuffing, swashbuckling. Even if dps is low, they may soak hits. This mechanic is just very very unwanted by everyone, since killing a mob quickly is the point of the game. Suffers being melee, and low range on skills. Requires heals due to high HP pool and slow recovery.
Wizard design = all-in-1 kits, have links, summon, buffs, AoE, and top CC. Contributes through AoE dps, top CC, or utility party buffs. Locked into worst stat in-game if they wish to boost damage, INT. No crits, but magic can’t miss.
Cleric design = main healers of the game, main revivers/ress of the game, main buffers, immunity, cc immunity, some cc. Contributes through keeping everyone healthy, and dps/cc. Some clerics suffer from hit-count skills, and hitcount divides through mobs. Has to pick either magical path or physical path, or full support - some classes have mixed skills magic/physical, inconvenient to stat and gear.
