Grotto I am not 100% if it can be soloed all the way through or not.
KBN easy ok NOW 10 levels higher yea.
grotto ez if not for third boss can be soloed 3rd boss is the pain making you bring healer. (at least for me)
as to kbn ez? easily soloed at level 75. When i said at level i meant at the instance level. Not the current level 85 cap.
As to rest any like hos colors or tosh first boss yes they cannot be soloed..
gce stops you of course at 4th of course at level do to needing 3 in party to not get hatted.
As to phoenix redemptions ... Why would you use them in EZ?
AC easy? could be soloed it just took forever on the twin bosses. (you could aggro them individually)
if you look i said those that can't other then ones like HoS colors, can be duoed. As in 1 healer and 1 dps.
Yes i speak from experience. As in I did all this myself as a R/S when I was capped at those instances level. Though I did give in and reroll back to r/m sometime after 85 level cap hit.
