7* rankup advice

Gr8TonyStark

I have the following 7 stars rn. None of them are r2. Also I still need 4 t4a for getting valiant. I'll try to explore act 8 or 9 before I step into necro. So, shall I r2 any of these 7 stars. OR, shall I focus on r5 my 6* herc, Kate, fantman (all duped). I don't play bgs at all. Thanks.

Also I'll get that 7* sinister in 8 days. Shall I upgrade him or dpx or hold for onslaught or someone?

Rank juggernaut and explore act 8 and 9.1 instead of necro

Shang Chi, Titania, SIM, Juggy, DPX are my picks
Any of them Ranked up is a Big W
