Personally, I can't say I'm tired of it as such. I mean, I rather farm tokens that lead to a guaranteed reward than farm things and may not even see my reward in over hundred runs. I had that a lot in early WoW. Wasn't fun, neither for me, nor the people who came help me on my farming runs. Sure, there was a big celebration when it dropped, but only because the suffering was finally over and we could go and do something fun instead.

What I don't like is that caps don't carry over in any way. I don't know about you guys, but sometimes I'm drowning in tomes (like right now, where I'm at 80 feast games just trying to get my fenrir pup, which happens to be RNG based >_>) and other times I'm more or less forcing myself to cap. More different activities to cap tomestones with would be appreciated as well. Capping with PvP instead of dungeons was a nice change of pace and helped a lot with not getting tired of the dungeons as swiftly.

And then there are these stupid moments where you are capped and have nothing meaningful to do anymore except for inflating your coinpurse with crafting.
Also, tomestones should, at the very least, be role capped, rather than having a general cap. It takes roughly fifteen weeks to deck out ONE class in tomestone gear, a time by which the catch-up patch is on the horizon. Equipping multiple classes is just a nightmare, even if you "have" a good amount of time on your hands. You're not even gating progression at that point anymore, because with STR accs for tanks gone, roles don't have overlapping equipment anymore, so you can't abuse it to get a headstart.
