I'm under no illusions about the fact that I won't still be there by the end of the week, but given that this is the first time this has ever happened I'm taking a moment to celebrate. Yayyy!! :D
Umm... if you're actually trying to get into tier 20 with multiple 4 star +10's, that's not gonna help much. You have to start 5 star merging and get to upper levels. At least if you're going to stay in tier 20. You're probably gonna need at least one 5 star higher merged unit to get in though.
Oh, I know, I'm not seriously trying, I'm fairly content to bounce between 18 and 19. I'm f2p and I enjoy building lots of different units; having to focus all my resources just to get one or two units to high-level 5* merges would suck the fun out of it for me. I was honestly just kind of surprised that it happened at all and decided I should celebrate. ;)
