I'm not very good at English, I will try my best.
IMO Things like DS shouldn't remove, those features make this game deeper than others bland ordinary Third-person Shooter games.
In FFT on average you probably need 2~3 months to grasp true essence of one class, and much more time to become a Pro. (except blaster I guess)
They(Dev.) already make some terribly wrong alter just because probably someone rise the topic loudly and many ppls seconded it. but most of times neither majority or Dev. knows better cause they simply don't have time to get soaking of every bit of this game.
I recall those Dev. bad changes of FFT.
like boost blaster's Minigun, reduce damage taken when use "Q "field.
cancelled gunner fast scope snipe(5 frames--5/60 seconds(my pc) won't drop move speed.
cancelled gunner different sinpe message (with or without scope).
more easier stack AR etc.
The devil is in the details.
Just like tank (your main class I believe?)
the Comet Rush ---> in 2/60 seconds(my pc) --> jump skill.
4 types Mauler DS with different hurtbox(2 of them required different frames input while sliding) etc...
Those hidden features make FFT very deep, ultra fun , and make a Pro a Pro.
But most important, In general scout's DS is not that OP compare with others classes.
for example: scout's DS stand almost zero chance when facing tank, even tank abandon bubble and bombs, you know that as fact as I do.
FFT do need some tweak, but absolutely not removal the fun and Features parts by doing so.
Some of your thinking were slightly marred.
In theory you can bind DS as Macro, but you won't want do that cause outcome will not good as you just click it by your own finger.
Assassin's DS required more skill.
Tank's DS is most hard to mastery due to many reasons, you may find the total damage is the same as you just keep press down mouse button if you not fully understand the mechanism.
At last I hope Devs. don't make any rush move. there are many aspects Influence each other, those tweaks needs to be inspection carefully.
even any vote appears lopsided one side.
Although kinda off-topic I would like share some of my personally
priority list of "hope can change"
(1)Gunner's Crouch, and Kick immune stun from tank's bomb,blaster's Rocket,scout's kick
(2)Gunner's snipe can penetrated Tank's Bubble, Headshot can penetrated buckler.
(3)Haze Bomb give scout immune tank's nuclear bomb stun and only taken half DMG
__ (half DMG only for scout class, immune stun only for the one who drop Haze Bomb)
(4)Scout's Doped Saber Chop can penetrated Tank's Bubble.
(5)Bubble Tank can be stunned by any stun mechanism except from Shocker.
(6)Blaster back to old school, no buff Minigun, no reduce damage taken when use Field.
I'm not familiar with Bomber and Commando. Although I think Commando is quite OP.
