Vampire lords are allowed - this is especially great for blitz, since they break through a lot on quick. It's hard to highlight other advantages... Overall, a very average (or below average) town for Jebus on HotA.
Well, the lords are only relevant with the week 2 growth, which is not viable for Jebus. HotA claims to have improved balance compared to SOD (and that's great), but in the end, they turned one of the strongest towns into a complete outsider on Jebus, which is confirmed by the statistics of town selection in the tournament..

Jebus isn't the only template, and on other templates Necropolis does just fine without Galthran.
In HotA, it is assumed that gameplay should be unified and not contain crutches for online.
That is true, but personally I very rarely play other templates besides Jebus (I'm sure I'm not the only one), so it's a bit of a bummer)
