Your servers keep dropping instances and I'm kinda sick of it.

A game that involves so much juicing and preparations can't afford such poor stability without any "check points" or "safety nets" to prevent the losses.

Agree 100%

I finally reached end-level maps last weekend. Having half of them drop, with copious investment and no form of restitution is unacceptable. That session literally COST me currency and experience.

At least give back the map when an instance is dropped server side.
