Exp excuse is strange. If exp is an issue - there always a lot of low-exp curious. I more agree with essence issue than this.
I manage my husbands account right now, since he is not active due to work. His exp was low as hell (always is, since i have no time to run around on his char), so at the day of the patch he went into -200 negative. Couple of minutes send him back at 800-ish right away. The bug with it going negative can be fixed, other than that its fine.
The fact that autostudy people will keep doing that is fine. Look at people who DON'T use autostudy please. It is us, who benefit from this system more. Tweaking exp to depend on wear would be great, but then again, I rather not have increased wear on items from stat, but stable wear, balanced with exp change based on that wear and maybe two stats to play role in lp gain (formula or depending on what i higher). Maybe decrease exp cost by third stat. Mental weight is useless and wear increase is strange thing to balance around (better to have static and balanced number there anyway).
