I joined a new alliance … which had just started with ~10 refugees from a different alliance, plus a bunch of new recruits, so our trophy score was way higher than our titan score at the beginning.
It was over a month ago, and I don’t recall the exact sequence, but I’m pretty sure we slaughtered 3~4 1* in a row, then 3~4 2* in a row, then 3~4 3* in a row, and finally by the time we started getting 4* titans, we had to work at it, after a couple weeks.
After that it has been a slower progression, killing a few, getting a bigger one (or two), having to let one go to build up flags, and getting a smaller one for that battle…Today we are letting a big 7* go, and we’ve only seen one 8* that we couldn’t kill.
Based on what I’ve seen, I have to conclude that titan score counts at least 2-3x as much as trophy score for titan size determinations.
Hmmm…does anybody know if the damage you do to an escaping titan counts toward improving your titan score, or is an escape worth zero?
