Because in my mind, it's one of the strongest builds I've ever seen. I'm not sure if you remember some of the insane things Pelrin was able to do, but I watched a few of them...

Anyways, I'm sure Neuro sealed alot of Pelrin's kills, but that doesn't matter for the point I'm trying to make. The point I'm making is that if we're talking about a fully powered lich/mummy then all these builds people have been talking about are NOT gonna win solo. You don't think people have tried? You think it's coincidence people like Ahtieli, Satebos, and Istendil simply DID NOT die? (9 man imperial gank squads aside). There are logs of GREAT builds attacking these guys solo. I seem to remember a log a rager did of him pulling Istendil into a no recall area, away from his zombies, and entwining him. Guess what? Istendil still won! Even Tavlin and Tzaritzawah took multiple people to actually bring them down.

So, to me, my point is valid. What's the best build to kill a mummy/lich solo? Transmuter. Because, with duo you can follow someone an entire log in, without them noticing if you do it correctly. That wouldn't work with a thief/assassin/or ranger. This stealth ability would allow you to track them into a very sticky situation. And that's when you strike. I'm not sure how you're seeing this differently than me, but in my mind that build is much stronger for actually killing a lich/mummy than any warrior or assassin I can think of. It all depends on the situation. In the right situation, you don't need neuro. And no, I'm not talking about waiting until they are at 1% health or link dropped... But then again, I'm not necissarily not talking about that either...
