I don't claim that good healers are excellent, but at least they have some.
One competant healer in a year in the Fortress is more than no healers at all for evil cabals. Plus you may have idiots just for sanc that is still better than no sanc.

As for paladins: if imms like a player behind a paladin, they give him temperance/retribution. If they want to screw him up, they toss him "hope". While the player itself is screwed, the rest of the cabal enjoys free sanc :)

Plus both classes may help with random heals.
Perfect or not, it's still better than no heal/sanc at all.

People like to talk about drawbacks of the Fortress but there also advantages which everbody seems prefer to skip.
Every cabal has it's own problems (and probably too much of them at the moment, so you rarely see expedictions to Hell, for example).
- Fortress has RP restrictions and idiot healers, but in return they have wider mix of classes.
- Empire has lack of healers and even if they have one, he is usually a cock and you may not have sanc at all. They also don't have access to mages, so no free haste/invoker-shields for everybody.
- Scion has less melee classes than other cabals and in general this cabal just ignores cabal wars or participates only when it is a clear win (there are exceptions of course)
- Outlander, while having wide mix of classes, have gay RP, so they just sit with their powers in camo.
- So tribunals.

Anyway, my point is that goodies aren't inferior in PK power to evils, but they have worse PK ratio, that's about it. At some point you really stop turning the world just around this one stat.
