Honestly, these exp campaigns, it just kind of wrecks low level leveling. It's great for 80+ or merit farming to cap stats, but for anything below 60 it kind of stinks.
I know a lot of people just want to hit 99 as fast as possible, but haven't most people already done that? This isn't like job point or merit farming.
It takes longer to get your skills up or gimps you when fighting the higher mobs as you watch a slideshow of "level up" displays, or you have to use sparks and spam a book for 20 minutes and consume what could be spent on extra pages or other items, which is completely inefficient.
I'm sure someone will say it's a stupid idea, but honestly, to some of us old time veteran (perhaps even new players, since it doesn't give you time to learn anything about your job really), it's a lot nicer then hearing the level jingle every other kill yet your skills are still lv 30 out of 50, 53, 56, 59, 62 etc.. every jingle.
Can we please get some sort of toggle / command to disable all experience bonuses from campaigns and rings? Or better yet, disable experience gain all together (I think Everquest 2 allows that), settable in the field like the merit toggle.
I honestly try to avoid any real leveling jobs below 70 when these campaigns are on. It's just.... waaaaaay too much.
