One of the things I was really looking forward to! I don't really like micromanaging a lot of things...I like smart, tricky characters, and I like arcane themes, but have never played a Wizard in previous editions because I didn't care for all the fiddly math of spell slots and such. Having at-will abilities, and "encounter" abilities (so long as they don't come off as "video-gamey" as 4E) would be my cup of tea.
Part of the problem was that I needed at least one invocation for EB, because that's the one thing I could (and was expected to) do. I needed another for my Tome abilities, thinking that would be the quickest way to add the most to my versatility, which instead ended up being redundant and seldom used. This "tax" kept me from picking some of the more fun abilities I otherwise would have snatched up.
Given a long enough timeline I would have picked up more, and lusted greedily at my future build full of so many neat tricks I could pull off...I'd never be as powerful as a Wizard, but what few things I had mastered I knew I could do reliably whenever I wanted. It just didn't work out as well as I had hoped?
I've never played a warlock so I always like reading about other people 's experience. I'm a bit surprised that you felt that the tome invocation wasn't great but redundant. Can you elaborate on that?
