My main is a Warcaller (Fighter/Chanter) I didn't take any subclasses (I should have taken at least Skald) but the character turned out to be a kind of a super versatile CC/Striker. The passive DoT chants are awesome and the paralyze blast is fantastic. I'm rolling with a Pollaxe, which gives him a bit of emergency tankability, and does good damage with good penetration. I don't think it's the best choice of two hander for optimization, but this cat thrives on versatility. He can sort of play any position on the team, which is really useful. Number 2 is a Ravager (Corpse Eater Barbarian/Helwalker Monk) Most of what I've seen is people going with shattered pillar for this M/C, but I wanted to go for the pure insanity of combining these two subclasses. As you can see, my main is a bit conservative so I wanted to just dip my taint in the volcano with this boi. He's fast as a blistered jesus lizard and he hits like a buick regal on the end of a stick. Corpse eater mitigates the damage he takes, slightly, and lets me throw bigger punchies more often. Haven't gotten too far with him and am pretty sure he is going to eventually just drop in every single encounter, but for now it's wild friggin' ride.
Number 3 I'm barely out of the intro with, but is a Hunter (Devoted/Stalker) Basically I wanted to make a HEMA boi with cool doggo fren. Also if you're counting the pet as a part of the character's overall output/effectiveness then this guy is a goddamned woodchipper. I picked Devoted because I wanted to be swangin (pokin?) my Estoc with the utmost effectiveness and -10 accuracy ain't **** for a fighter/ranger once you get past like level 5 and you don't really need access to ranged before then. I picked stalker because of the buffs you get for being close to your fluffy pal. I picked a wolfboi because damage, they don't get in the way as much as lions, and I <3 doggos.
