I've spent A LOT of money on PRO and rerolls awhile ago. I knew buying rerolls was a huge waste but not like this. It's actually insane, even with the price of CC's being as high as they are.
I was super lucky getting an amazing Thundurus and possibly other legendaries straight from the quest but all of my re-rolls for anything else have basically gone to waste and after seeing this, I don't regret not buying more.
With Kup's idea, it would make PvP more competitive in the long run, and it wouldn't be overpowered as it would only hit the minimum usability of a few legendaries. If the grind isn't outrageous either, it would give content for everyone to work on or it would give people a reason to actually spend money on the game to buy RRs. I like this idea better than raising the cap per RR because that only helps a select few who've saved enough money/RRs plus the lack of grindable content wouldn't attract people who've left the game to come back, and overall just doesn't have enough incentive to get me to play the game again. I can't even be bothered to do my daily Solaceon to get RRs right now.
If I'm going to waste money buying CC's to buy RR's right now or with the RR usage cap. I'd better off investing in a gacha game instead :v...
