Once more people get lv55 and start running raids, there won't be really a problem with not enough of those upgrade items in market. All other servers have saturated markets and there's always at least 100 on sale, and not too expensive either (enhance protectors will be your bottleneck to how fast you can enhance anyway, enhance chips won't)
Once the game matures a bit more, average player will be able to farm at least 10-20mil per day, so spending even 2mil per enhance is pocket money really.
Problem with that is, That evrything is locked you can only do casual raids and already did around 50 of them
we basicly just got the skin of the game.
