Return of Reckoning

So I played this agessssss ago and I remembered I enjoyed the game, but I'm stuck on which class I might get more enjoyment out of. I'm thinking between Engineer, Ironbreaker, Shaman, Squig Herder, it maybe Warrior Priest.

I'm probably not going to be joining any guilds anytime soon, and I usually find myself doing small rvr, following the rvr zerg, or just alot of scenarios.

I'm leaning most towards Ironbreaker or Heals Shaman, but not sure which I'd rather do at the moment. Anyone got any thoughts? Which is more desired late game for stuff, difficulty curves, whats more relaxing to play, etc. I'm mostly just going to be playing casual, not sweatyness here.

Heal wp is always welcomed and relaxing.
Shaman hard imo and will be kiled lot of times not chill at all.
Ib needs good gear to be chillish but you have a lot of stuff to do debuff cc guard etc.
Engi, sh are fun to play easy to learn hard to master especially sh imo.

So i recommend heal wp always welcomed chill and relax fast level with leech heal and gold conti in every zone everybody wants you and love you and you are not the prior target.

If you wanna chill but you need an option to the future to ne master than SH. You will die a lot of times but if you dont care its fun and chill imo.
