I think OTM seriously messed up raising the level cap to 200 so quickly because If you think about the xp grind is in serious need of attention you should be able to level without Lix but it will take you 1week to get 1bar( sarcasm ) another thing would be think about all the new comers with how horrible the xp system is right now do you really think they will want to grind to level 1000+( sarcasm ) which makes some people think oh dang 0-1000 with this xp system no way i quit which isn't good for business imo.
If u assume everyone is a serious mmorpg player then yeah but there are causal players. I have high level chars but I'm more of a casual player now and I've grinded my alt to around 100 and I'll carry on while I have fun do other things too, no matter if u use a xp lix or not your still doing the exact same thing. It's more about having fun for me now and not all about levelling to a crazy high lvl and there might just be ppl that think this also, don't assume that everyone thinks the same way u do
