Rank up Reinier now or wait?
Currently I have a 1/2 mythic reinier, and have enough to get him to mythic+. However, I haven't gotten a copy of Reinier yet from the all heroes available as of yet, and purchasing a dupe of him now would mean that later on, I'd have another reinier copy doing nothing for however long, probably forever. I can also start building Phraesto right now, however my next shot at getting reinier is in 17 days and can go up to 60+ more days if I want to get him through the guaranteed drop. What should I do here?
