Point of order: taken out of context, the words you quote from my post make it seem as if I was advocating for other heroes to be able to do what Wu does. I certainly was not, as you can see from the bit where I said:
To the list of unique heroes that includes WK and Guin I would add Alby. I’m not convinced we need more Guin-like tanks, I’m not convinced we need more revivers like Alby, and I’m not convinced we need alternatives to WK.
But I’m still not sure. Why is it a bad thing that there are some uniquely useful heroes without whom players will be disadvantaged in some parts of the game?
Edit: Second point of order:
Hmm. In the end, over the long term, using WK will increase your average Titan score, yes. I think the point the poster was making, however, was that in the short term, over individual Titans, using WK can harm your Titan scores because of the increased variance he brings. Plus, of course, he is fragile - his propensity to die early somewhat offsets the expected increase in Titan damage score. (Only somewhat, I think, though I’d be interested in any proper analysis anyone has done on this issue.)
