So far I’ve played:
Necromancer - Wouldn’t suit you. Aggressive and not boring doesn’t suit minion based builds, and that’s what Necromancer does.
Poison Marksman - Wouldn’t suit you. I don’t think you really want ranged or DOT focused, much less both. You want the “crunch” of satisfying melee hits smacking down enemies while you’re in the mix of combat and watching them fall immediately and directly, is my read.
Healing Hands Paladin - Too powerful, too easy, doesn’t feel chunky enough, wouldn’t be your cup of tea.
Glacier / Cold based Runemaster - Now we’re talking. Freezing enemies, blasting them away with giant chunks of ice bursting forth from the ground, actively building the ablative layer of HP via Ward that enemies are tearing through, it’s aggressive, does a lot of damage, it’s very fun, satisfying, and not boring.
The only issue is, it gets too strong eventually. You start to have enough ward and build enough that you’re never in danger, you don’t need to dodge, you can just spam your abilities and it’s just a matter of how long it takes the enemies to fall down. So while it is strong, aggressive, fun and satisfying in my book, I could see it becoming boring for some folks.
Melee Werebear Druid - Now this on the other hand, is aggressive, chunky, fun, satisfying, and not nearly as powerful. As such you still have to dodge big hits, much moreso than the ward based Runemaster. You tear enemies apart with your Bear Hands, leeching back your health and rage by staying in combat and dishing out damage. It’s tremendously satisfying to play in my opinion and even if it’s not as powerful as the Runemaster (or even the Spirit Thorns Spriggan I tried along the way) I feel like that style - health based, melee based, with good “chunky” abilities that are satisfying and can obliterate a crowd of enemies instantly - is ultimately what will best fit the playstyle and preferences you’re describing.
