Sim Mayor said: The best advice I never heeded was to get a 2* farm completely up and running before going whole-hog on champing 3* characters. You get so many 2* characters that will just add a barely noticeable trickle of iso if you're not farming them, whereas with the farm you start building up HP, CP and a bunch of good basic 3* covers that free you up to focus on some of the harder to get stuff.

Very solid advice here. Only thing I have to add is that hitting the seed teams in Lightning rounds is an excellent source of ISO and two-star covers, keeping the farm spinning.
Heck, with the ISO rewards from SHIELD levels I don't Think farming even leaves an ISO deficit anymore in the long run.
