Should i keep cwl medals

Hi guys, i recently got to th11 and have been keeping cwl medals since th10 to upgrade heroes (because on th9/10 they arent too expensive to need hammers ~at least for me~) but i have seen a lot of posts and commentaries here that on th12/13 the heroes are really annoying to upgrade and now im wondering if i should keep the medals to buy a lot of hammers on th12/13 and upgrade them really fast (even though i need to wait 7d to buy another hammer, that would be almost 2 levels of heroes per week, 1 hammer per week + 7d of hero down) and if yall agree that i should do this, for which th should i use the medals? Th12 or th13? Which one will i take more advantage? Currently this is how many medals i have, i think that till th12/13 i will have around 2k(i dont buy gp) and currently my clan is on crystal 1 league 1 submitted by /u/arthuzindotrash [link] [comments]
