Interesting!, thanks for the data. I've not tried Survival mode yet.
I'd be tempted to give it a try, but it will play havoc with my ability to field teams for my guild Brawls, I play Silver wild, so I can't afford to lose any cards, I have no duplicates to spare and I need to rent to fill gaps as it is.
What league do you achieve in Wild ?, what are your summoner levels, and how many duplicates (summoners) do you have at your desired level ? Chaos summoners are affordable, I'm tempted to try at silver level, I can field two of each CL rare summoner at that level.
Or maybe go wider in Bronze, but I don't think I'll earn much for Bronze.
Hmm, reading what I said above again, maybe the answer is staring me in the face. If I fill the gaps in my Brawl team, I save on rentals...I think that is a certain gain long term, verses a possible gain in Survival
