I'd figure I'd share my full thoughts on this Legendary Hero banner now:
Hector is cool and all, but I'm mixed on him being our Legendary Hero. On the one hand, Legendary Hector is fantastic skill fodder: he has Distant Counter AND Vengeful Fighter! His new Armads looks pretty good too(yep, we now have three different Armads weapons in Fire Emblem Heroes now)!
On the other hand, the fact we now have three Hectors who are the same weapon type AND same kind of unit class is pretty boring. I was hoping we'd have another hero with an axe for a change or just another character get some spotlight for being the first Armor Legendary Hero. Bolverk Xander would've been pretty cool. Alas, looks like Legendary Xander will happen another day.
I'm definitely pulling for green in this upcoming LH banner. Legendary Hector is already a unit I want to pull for his skills and/or the potential to being a really good unit seeing how the past Hectors are still among the best units in the game. There's also Brave Ike, and I want another one because I'm trying to build a Nowi right now who only needs Steady Breath to finish the build (I also wouldn't mind pulling even more Brave Ikes too since those could be used as Steady Breath fodder for the other dragon units I plan on using for my Dragon Emblem team).
I only wonder whether or not Legendary Hector will power creep the other two Hectors we have right now (I mean, Valentine Hector kinda power crept the original Hector in Attack, Defense, and Resistance, but not so much in Speed and HP). I hope the other two Hectors will have access to Thunder Armads through weapon refinery in a future update, because that could be useful to those that could potentially fail to pull Valentine Hector for this coming banner).
