Please look at my Roser and tell me what next

shadow310574

I sold my 2* to bring all my 3* to lvl.166

I think I have 8 full covered 4*
(Cho, Hb, Xfw, IW, Cyclops, Star Lord, Iceman)
and a few with 12 covers

Im at day 400, thats why I sold my 2* so i can level up my 3* faster

But what next ?
leveling some 2* first ?
bring all full covered 4* to lvl. 200 ?

Please look at my roster and give me some tipps !!
