Wait, wait. The druid 'nuke' set gets balanced on stamina on the assumption that the druid can turn into a bear and... nuke? Something's wrong with this picture. :unsure:
Nah, it's just meant as penalty for those who chose puny night elf over mighty tauren.
On a more serious note there's still plenty of room to customize your sets and other pieces for stamina or whatnot. The stamina has been omitted in favour of other stats which to me seems justifiable - we are pretty high survival class with two instant hots, and as long as the stats are there somewhere I'm content with a bit lower stamina in favour of spell power or resilience. :)
I guess that we can say feral druids are intended to have more life than their resto and balance counterparts.
However... If you look at the rogue Netherblade set, it has a total of 149 stamina, 1354 armor, which is far larger than the feral druid's set. This suggests that HotW and Thick Hide are being figured into feral druids' armor. That is: 124 stamina * 120% (HotW) = 149 stamina; 1137 armor * 110% (Thick Hide) = 1250.
Which was of course, discussed earlier in this thread, but still, sigh. Nothing like working the numbers for yourself.
