The HP may be atrocious, yes, but that is compounded by the fact that this setup gives me a whopping 16k autoheal - literally what doesn't kill me outright will just be shrugged off.
Ganesha is there specifically to tank stupidly big hits, and the massive HP deficit can be rectified (to a point) with plus eggs. This team's major weakness is probably just its burst potential, but with everyone and their mother having at least one TPA damage shouldn't be lacking in the slightest - I suppose the strategy would be much like a stall team's, only infinitely faster since the multiplier isn't complete ass.
That said, maybe running UVO'd Raphael would probably be better, if not for the fact that he is a row-based monster with an absolutely ass active in a team that is largely TPA-based. Let's also not forget that the highest possible multiplier with a Raphael co-lead would be 5,4x and unlike the RGB archangels there is no Dragon Emperor for big bursts. Plus your autoheal falls to about 9,5k, which, although good, is not nearly as much as the 16k - especially when considering the fact that your now have double the health and a third of the damage, with no gravities and no Morning Stars.
...now that I think about it, Raphael really is the worst of the archangels, simply because he exists in a niche (light rows) which hasn't been really developed yet, even in that niche he isn't the best option and he doesn't have a big nuke like Lucifer nor does he have a Dragon Emperor like the RGB archangels.
Super Uvo Raphael when.
(Also, I think I saw someone clearing Hera Rush with a similar team not too long ago, so I'm pretty sure it can work with at least *some* lategame dungeons.)
