Gold? Nah sitting on 17mBut isođ 0
Have you used it all? Mine is expiring.
It depends a little. I rarely have a problem ranking up champions as long as I don't do too many rank-ups within the same class too close together. R3'ing my Warlock this last Level Up Event dried up my Tech ISO completely so I'll have to wait for more before ranking up my Punisher 2099.That said, I feel like my ISO has improved significantly with the introduction of the dual crystals. I save up all of my 4* shards and just use them when I need more ISO from a specific class. I'm down to about 2 million gold for the first time this year after some hefty rank-ups, but the gold boost event will fix that since I have a bunch of crystals saved up.If you have the option to grind out the featured arena, you eventually get a full champ (both a 3 and a 4*) and not just the 1 sig point version that was in the arena before. That's a fairly good and reliable source of ISO for me. Plus, units and gold. I try to run both featured arenas each week and that keeps me fairly topped up in the various resources.
For everyone who's okay on iso, I do have a question, what is the best place to get shards/iso? I can't keep up even if I only use only class iso exclusively.
