Yes, 50% damage reduction is really good. Effective 2x hp/2x RCV, but better against gravity. It's basically the gold standard for damage reduction in an LS. Also, 6-comboing is an easier condition than healing 50k on a team without an RCV multiplier. The healing requirement likely means matching exactly four hearts, which is a big problem for example if you also need to FUA. Neither beach Gronia nor Wetatron is particularly great, nor would you expect them to be I think, but just for fun, I'll take up the gauntlet in comparing them. I have a Wetatron, and after thinking a bit about how to make a team, I've come to the conclusion that she's basically terrible. Let's assume you can load up your leads with heart enhances, so that just the two of them can easily get you to 50k healing when you match four hearts. Great, you've got a very defensive team with a pretty high attack multiplier. You're still dependent on the rest of the team for everything else. 1) Damage. Weta has basically no personal damage. So yeah. 2) Making hearts. You'll need to make hearts sometimes to serve the LS, and even more if you need to FUA. Unfortunately, Weta's active is 6-year-old garbage. Why would you want an active heal on this team? Why can't she make hearts? Of course you can inherit something on Weta, since her active is just 4-turns. But that's basically adding 4 turns to the CD of a good active. 3) Making orbs for damage. See 2). 4) Basically any utility awoken skills. Yes, that's right, Weta has neither offensive awoken skills nor utility awoken skills (unless you count two SBRs). Also no TE. How is that even possible? Even with the freedom to go any color (why bother staying with blue, since Weta herself deals no meaningful damage), I don't think there's any way to make the team look good. That's setting aside the point that, again, you really want 7x6, +combo, or auto-FUA in a lead to deal with with those bosses that have combo shield + resolve + void damage. For veteran players, I think the main value of these kinds of leads is that you can challenge yourself to clear A3 with them, or something like that?
