Unless they release content that needs Dehya's specific kind of tanking like tomorrow, she can't really support the way she's meant to. All of the content we have right now is geared towards optimal DPS bursts in the shortest amount of time possible. Dehya helping us survive a smidgeon longer without a shield and giving us a tad bit of interruption resistance when she feels like it doesn't really do much for most teams.

Not to say that you won't be absolutely fine with her in overworld and most domains but most people don't want their favorite characters to be 'just fine', they want to build a team around them and make them shine.

Dehya mains have my sympathies foreal foreal, it sucks. :(
