QB mentioned month ago that sappers will get additional totem types (hp/mana/energy).
And that's why I'd like to propose also additional thrown weapons for sapper.
There's a flashbang which is pretty useless in most cases: expensive, short AOE, no exp for using it (7exp after 3 successfull flashbang ? another joke) A frag grenade would be very handy, and as mines are pretty useless on people using blocks, nades could be also blocked.

Whatcha think about that ?
