I think you'd be accepted well/treated well, I've taken multiple months off at a time before due to burnout, while not comparable to your situation, I did have trouble getting back into the meta & getting to know new game stuff as you probably will. Most the time people treated me well whenever I had to re-learn the game, of course there's always that one toxic guy, but most people are pretty nice as they don't want to scare off more people from the already small-ish playerbase.

Yeah, you are right.

I got exe'd for having kingslayer II but being confused, so maybe don't use that title.

Patch it was because you played during the 2nd Year that you were awarded the Kingslayer II title, so they assumed that you still knew how to play and killed you for not playing up to their standards. (The current meta is to claimtrain during the early days, let Prince deal with Evils, and push King to point)
