Not true. I don’t have anywhere near the ascension mats to ascend all of my tc20 heroes like my 3 domitia dupes or my quintus. I’d rather just use 4 star heroes instead.
Instead of wasting roster space, and then I’d have to waste even more gems to expand my roster space, giving me a chance for an hotm or seasonal hero would be amazing. Sure, there’s a high chance it’ll turn into a feeder.
But there is literally ZERO value in a useless 5 star hero rotting there at 1/1. Actually, it’s not zero, it’s negative, because it’s wasting a roster space.
IF there was a way to turn rare or epic heroes into 5 stars (without the use of gems), I know I, for one, will never spend a single dime on this game ever again. Why spend when you can just get all the best heroes for free?
I mean, just looking at the proposal from OP, if I were to run 4 TC20s, I could get 146 epics and 36.5 5 star heroes per year. Assuming that I didn’t want any of them, that could be turned into 146 + 365 = 511 EHTs. At 1.3% chance for HoTM and 1% chance for seasonal 5 star, that’s nearly 12 free special heroes a year.
I’ve spent upwards of $300 on this game, and played actively for over a year, I’ve only got 8 non s1 5 star heroes.
So this proposal alone would be better than playing and spending $300 bucks. I can’t see how that’s undesirable. It’s clearly way too OP.
edit: Actually it’s even worse than my calculations. I forgot to account for the other epics and legendaries that can be rerolled from those 511 EHTs.
511 EHT = 7.665 season 1 5 stars and 135.4 4 stars.
So that’s an extra 76.65 + 135.4 = 212 EHTs from the heroes from those EHTs (the 3 stars become high exp feeders).
From those 212 EHTs, that’s another 4.876 special 5 star heroes and 3.18 s1 5 stars, 56.18 4 stars.
With those s1 5 stars and 4 star heroes, that’s another 31.8 + 56.2 = 88 EHTs. Which is another 2 special 5 star heroes… and so on. But I’ll spare the rest of the calculations.
Just that alone is nearly 19 special non s1 5 star heroes per year, along with hundreds of high exp feeders.
