FYI, from i27p6
"Weapon powers now play a draw animation the first time you use a weapon after your character is has been in an idle / non-combat animation. With typical mission pacing, this should mean each weapon will only play its draw animation the first time you use it in combat on a mission map, unless you idle somewhere on the map for long enough for your character to return to the idle state."
So don't worry about redraw, its a non-issue. Assault Rifle/Tactical Arrow is a really strong all ranged blaster option that is quite popular if you wanted to play a pure damage role.
