Thing to remember about the gnoll whipmaster is it gets an XP bonus with ranger levels, if you reinc it into something without ranger levels you may lose levels. Of course, I happen to think the gnoll whipmaster is a great first tank. 2H tank is just hard without excellent gear. You could do a 2H gnoll with spear but it would probably be pretty meh. Lashes are nice tanks to have around since their debuffs make the rest of the party better. The Gnoll character will help you get to 40+ faster which will get you to better subraces. Though, gnoll is pretty good for an open subrace.
