In honor of the first non-faction Legendary to release in a bit, here is my current thinking on Legendary troop tiers. Many, many updates since last time, in large part thanks to the feedback you guys have provided. Thanks again, and keep up the comments!
(As for Gruz, I tend to be optimistic on new troops, but I just can’t see a niche for this guy. Single-target damage and status inflicting tends to be a ticket to bottom tier, and Gruz is no exception.)
(Also note the slightly-tweaked tier guidelines.)
(EDIT: latest list can be found here)
Tiers:
S: Invest at will, you can base a team around these troops through the endgame.
A: Overall not as strong as the S-tier, these are strong complementary pieces that can be used on many teams.
B: Niche troops; these are very good when plugged in alongside other strong options (they usually have 1-2 BFFs), but can’t stand on their own on endgame teams.
C: Usable, just not good enough to be B-tier. This is either because their abilities are not up to snuff, or there isn’t a meta team that can use what they bring to the table.
D: Do not invest in these, you can center better teams around your lower-rarity troops.
