Magic said: Having dedicated slots for farming is perfectly acceptable way to approach the farming itself but fairly costly. You have 6 slots used on it. While at the same time there is no benefit of having the 2* leveled for actual game play. You just need to have them all at 1 cover (which is usually the case for a very brief period of time) for DDQ with the CP node and any trio for the 2* nodes. The 2* node in PvE is equaly easy with lvl 15 and lvl 144 2*. If you decide to cycle them within the same slot you save lot's of HP for other heros. I also level them as the covers come so I never treat the iso they give as an extra and as soon as I have 13 covers they are championed again.

Looking at your roster, you are also approaching a gold mine of 4* covers from a bunch of your 3's as they reach level 183 so you might wanna check whether you'll need any roster spots for those covers (although it looks like you might be covered already).
