Ascending these troops would take a while for anyone waiting for a new kingdom to be released to finally use Gold Keys, but a player could use the keys earlier and maybe some gold to ascend such troops once they are added into chests. But in the long run i believe it’s better to wait, a rushed decision is rarely the right one.
We must remember that the first Bounty Week was easier, requiring less points on each tiered reward, so this next one should be a little harder in this sense which makes ascending these troop a better deal as soon as possible, but i would, still, refrain from using an Orb… Because despite the extra score on the old Bounty troops it’s profitable to buy the newer Bounty troop because it gives double score.
