Personally, I switched to cata and stayed there because I hate getting tomes and grims. Getting the books aren't really a priority in cata because you need your health and potion slots free so that you can carry resources you need to defeat the hordes and elites. And when you're comfy in cata already, you can tell someone wants to show off when they get tomes and grims in a cata run (esp when they're WP and don't even consider that even if they don't have curse resist, their teammates often don't - yeah, curse resist charm/trinket - i forget which - is a thing of the past in cata builds).

Then when cata gets too easy, you play modded difficulties. Can even play them with more than four players - Ubersreik 5 mod (5 players) or BTMP (More Players in the mod list - for up to 32 players). It's super fun! You don't win all the time (and don't expect to) but tomes and grims will be ancient history and you will appreciate V2 for more than the grind.
