No no it doesn't, that makes sense. I do have drops to consider, especially with my wanting to app Shin-ah (as said on plurk/it's even on the reserves) because of, well, precisely what you said. Same reason why I apped Aang, whose being less active is just far too noticeable and lets down his entire cast, so it wasn't fair to keep him when I couldn't give him the attention he needed.
I... actually figured the lack of replies was simply because Ana's characters had just returned so we had threads ongoing, Celen's away so her charas don't count, and Robin had them covered and we chose to spam on the following log? The rest aren't really so compatible with him - charas like Torin who doesn't really know him (and we know Aramis hates their lot), Elsa who was afk, Wan who doesn't know him either, etc. I don't know what the point of naming that is, just that I got a different impression of it? If anything I'd argue against my other characters not being tagged for this...
Which I agree is an issue, and much more noticeable now that it's ETERNAL UPDATE TIME. Same thing happened with Mako when LoK was last airing, the whole cast kept jumping all over the new developments and we had constant updates. Or back when Neal still existed in OUAT, we had many updates and things that stole our attention at the time... A mix of this + Merlin/Aramis being far far stronger muses and extremely easy characters to play means that they're constantly all over everything, and the fact that the casts have mixed doesn't help, as it only makes their activity higher and means they have more and more plots to go.
If it... helps at all, my current oldest tags are all from them too? I take days to get to their backlog at times too. Right now I've had less tags than I did in a very long time (think going from 200-230 on any given day, to 120-150), a number that to me is very manageable (I can get to that amount in what, two days) and the only reason I haven't tackled my backlog properly was a) having to do stuff irl and b) getting caught up reading AnY. I'll make sure to get up to date on things, especially with a new log and changes to play out coming up!
All that said, which I promise isn't to say oh my GOD I HAVE NEVER PRIORITIZED AN ARAMIS THREAD IN MY LIFE!111!1 /CLUTCHES CHEST but more to give an idea of where I stand on this and what my threads status is like, as I mentioned first of all, I do agree this is an issue and did have drops considered, since keeping weaker muses means they suffer a lot from this kind of thing.
At the very least, there's only a month left of Musketeers and our hype should die down a little by then without that urgency of oh god this one plot happened WE WANT TO EXPAND ON IT IMMEDIATELY LET'S GO, and help even out things. I definitely do want CR with my other charas, even if I can't play them as regularly, and I'll make sure to keep this in mind and improve the activity of the non-musketeers/merlin boys.
