Probably the most useful thing I've ever read on the forums.
It confirmed a few ideas (bear being the best dmg dealer at later levels) and helped me figure out a huge problem in my pet usage (couldn't figure out why my raven hardly flanked and was always out of power ).
It is funny that for most situations, whether group or solo, I will be running with either the bear or the raven which are the first pets you ever get.
I will say that you nailed the following points:
1. Lynx is great between about 30 and 50. Surprise strike is just beautiful.
2. Bog Guardian is a bit difficult to handle and position which is a turn off for me.
3. Sabercat shines in things like skraids and bigger skirms. The AoE dmg combined with a warrior allows me to roflstomp duo skirms by myself because all that AoE dmg keeps the 10 mobs off me unless I go ISG, lightning or ents too early.
One point that I think you could have touched on was the fact that ranged auto-attacks on the bog guardian make kiting possible. Most pets just end up chasing the massive mob you are kiting so the ranged autoattacks are kind of nice in tricky situations. Also, it is the only pet that can provide flanks, dps, and FM's while staying out of AoE range.
