Paired with a lucky Corsair, you can have as many Indi-spells up as times he can reset you. :P
Back on topic, it's been mentioned but most shout groups usually have a WHM with them. WHM is far from obsolete; we take one with us to everything. Our group's mythic WHM is particularly handy for things like Incursion; if a Stun misses and a TP move gets off, a quick erase-ga or two from them makes life much better. But in general, WHM offers a ton that makes them useful - AoE burst healing when needed, barspells with the AF3+2 set for the element immunity procs, Arise, Cureskin, etc. WHM is and prolly will always be the best healer overall, especially paired with good support.
