1st: Polearm + bow : greedy beyond belief. Archers dont carry poles, or 2handers. Only greedy people do that. Archers kill people from range. To be completely honest, hybridization is admitting you arent good enough at anything to rely on it 100%
2nd: Theres SO many reasons to swap into 1st person: Shooting thru windows, down from roofs, thru fences, in a crowd of teammates, to name a few. Not doing it is so severely limiting yourself as to be....well, ridiculous.
And all the tunnel vision arguments are null and void, since the Viewchange button WORKS BOTH WAYS: press it once to go to 1st person and then again to go back to 3rd.
Or if it REALLY bothers you, and you MUST have a huge melee weapon as an archer, just edit the backstored items out in your game files...
