A better 4*DDQ?

WalrusBrigade

This has probably been posted already, but it came to me a few seconds ago and I wanted to get it down before I forgot.

I'm in the 3*-4* transition, which is a slow going as we well know. The rate at which I get a specific 4* is really slow (not as bad as 5*, but still slow) in large part because there aren't many opportunities to grab guaranteed 4* outside of 1000 PvP rewards. I'm hoping to get to a point where I can get those with some regularity without shields, but that feels like a long way off.

But what if, in the 4* DDQ you had the option of getting a single cover for the next clash required character rather than getting a LT?

I know that would be bad for those people trying to get 5*, so it would need to be an option, but it would allow people to specifically build their 4* roster in a manner where they could predict the result and also where it could help sustain their participation in clash.

So, how terrible an idea is this?
