So, my sporebat has remained in the stables for the time being.
But, from what I've heard cata 5 mans should be harder, presumably requiring some degree of strategerizing*, possibly(?) even bringing back a CC element, so you never know - sporebats might become popular again...**
EDIT: From the RP'ing side... I also loved Zangarmarsh. Pretty much any zone with giant mushrooms is okay with me (reminds me of Nausicaa / Valley of the Winds)


*At least until all the 85s are several tiers into the new end gear, and it all reverts to EZ mode
**When I say "CC" I'm speaking very generically here, since obviously in this case we're talking about slowing enemies down not paralyzing them, but same general idea...
