I know... but it's for Teleport. I'm not always inclined to walk the entire way to Baal, Nihl, or even Mephisto.
Oh and I'm going Conviction instead of Fanaticism (Faith bow on Act 1 Merc for some Fanaticism).
Tele in uber-trist = Not needed. No resistance.
If you tele wrongly, you might get ALL 3 ubers spawn (and their crew) on you and the lag might be enough to hose you especially considering you don't have overstacked resist from COH. Especially with uber smite gear, you might not have FCR gear to make fast teles to escape.
Easier to walk. To date my last few rounds have me edging to meph and he spawn less than 5 skeleton mages on me and he is easy meat. My first game this year (after a near 3 year absence) had me procing meph the wrong way and I got surrounded by at least 20 mages.
Creeping slowly and take your time.
Don't tele.
Merc in uber-trist = waste of gold to ress.
In the end for ubers, you will be doing it solo.
