Yeah, I'm having a lot of fun with the alchemist summoner too! I like the sword summoning spell too, so cool, but has longer CD and lasts much less, usefull against bigger guys.
For those who want to try something different, I'd like to suggest this tiny
mod, which essentially gives you little spider-like bots to summon in place of imps. Fits better the alchemist theme I guess? Oh yes, they shoot and don't need corpses to summon (very usefull if you do a lod of ice damage and crits)
Also If you're looking for another twist, this other
mod (by the same person) takes out the alchemical golem and gives you a smaller-weaker version instead, but you can summon 4 of them instead of just one. This one I'm not personally using, though.
There really are a lot more mods out there, but some are very OP, so don't overdo it
Oh, and for all of the nostalgic ones, you can expect a necromancer class coming sooner or later
