Hello there.
Well, maybe a silly idea, but did anyone consider to get another backup weapon with several specials (burts, fling, fa) and swap it for his belowed rifle after the great opening, ie. AS?
Why: since I spend more and more time in mp, namely doc, and I'm casting healing nanos etc. in a chain fashion, a special which is not blocked by casting would help from time to time, especially when soloing. With SPS one can squeeze out a shot during the nano recharge, but still the damage output is cut down.
So some pistol or SMG might help.
And it's even not new: Simo Hayha, a top Finnish sniper with 500+ kills, used a SMG as a backup, too, when he was hunting Russian soldiers in frozen Finland forests during WW2. :-))
I even tried to use a fling rifle, but it doesn't seem to work, as the fling refresh was horribly long, well practically it means one fling per shot which is not worth it. I don't believe that the specials recharging formulas I have seen so far are OK, since they don't count with the user's skill vs. weapon min requirements ratio, and anyway the Peren just had 11 sec AS recharge as far as I remember, even if I used it with a big OE penalty.
Anyne actually tried it or thought about it, and if yes, what are options and results?
