I totally agree, don't get me wrong. By the time we get 4geta and G4ku, japan will have SS4 Gogeta, who gives everyone infinite ki and 700% HP/Attack/DEF or something stupid like that, and everyone will again say "wait for Gogeta!" and so on until they completely run out of characters (which is not too far off btw, which is slightly worrying, no?).
It's just something everyone has to decide for themselves, what's worth it and what isn't, as it always has been. For me, the Rose/SVB banners are close enough that going all-in on Omega isn't worth it, considering he's on the Rose banner too, and I don't like to spend money on this game (although I do, and I kind of hate it, but I digress). BUT I also have a fairly strong box, lack of gods aside, that lets me do most content with the help of a friend lead (of which I have plenty now).
That said, gacha fever can strike any time, and for all I know this time tomorrow I've thrown 200 stones at Omega with nothing to show for it. Who can say.
