I think it’s time to make this a regular feature. I know we have 4* pvp with new character releases but a large percentage of the player base are either using a loaner or an under-covered 4* feature. . The game right now has more 4* characters than 3* characters and yet pvp is still primarily based on 3* features. This could at least break up some of the monotony and maybe even cause us to fight some different teams once in a while.
I was all for this for a long time.
Then they occasionally run 4* PVP’s that people have leveled (ie: not the new release ones). Elecktra, Dino, Howard, GR, DPXF.
Nothing like matches that take another 5 minutes each. All for 4* PVP’s, when they make the other two support characters a tier higher for many players (to make the matches shorter)…which means they need to make 5*'s earnable outside of RNG.
Why not add pvp four star on a separate rotation so we have dual pops and dual seasons 
four star pvp can actually award four star covers past the first couple people.
