Viper or Winter Wyvern?

I will choose Winter Wyvern if his items are carry items

 

viper with manta ehehhee

 

Viper if carry.
Winter if support.

 

Viper for me i still not cross sword with winter

 

Viper for me , why?
Viper had 3rd skill that gives magic resistance / if you hit him , you will be poison tempo.
Also his current base damage is increases bcuz of 2nd skill, plus unlimited poison of 1st skill
Winter wyvern?
WW is jst good on support , but somehow many people making this hero carry , cuz if u had aghanim's he can use the 1st skill unlimited (Flying), But it drains your manas. Also WW had low defense so, he can be easily killed by carries usually those poisons/high attack type.

 

Well he have his ulti which is Winter Curse, after using it he can run.

Winter Curse,
Winter Wyvern freezes an enemy in place while striking those nearby with a maddening curse which causes them to attack their frozen ally with increased attack speed. The frozen ally and those cursed to attack their ally are immune to all damage from their enemies.

 

If im the viper , ill just build bkb and ill end yah easy counter

 

And yeah you wont win if you just run whole game

 

Exactly , if winter runs .. I can free push

 

Viper has the range advantage so Viper
