Let me start by saying you play all your characters well, this isn't an issue about characterization, but I wonder if you wouldn't benefit from playing less characters than you do. It seems as it is you almost always prioritize Aramis and Merlin's tags and boomerang tag with them for days while you often wait days, even weeks sometimes, with getting back to your other threads even once.
I know you've been busy irl, that The Musketeers is an ongoing series and that you recently got a new castmate for Merlin and I understand that's exciting, I do! But to me it seems this isn't a recent issue but an almost constant thing. It's to the point where I feel I maybe shouldn't bother pursuing CR with your other characters because you don't seem to particularly want it.
Looking back at Aramis' latest updates in the blizzard logs I think it's telling that so few people replied to them: it's discouraging when you keep posting new threads for one character, encouraging people to tag them while ignoring most of your other threads. If you scaled back the number of characters you play I think you wouldn't be so constantly bogged down by threads and you'd get more threads with the characters you're most interested in playing.
I'm sorry for the tl;dr! I like playing with you and I like all your characters, which is why I'm writing this. I hope it doesn't come across as too harsh, as that isn't the intention.
