Poison for 2 seconds.....for WHAT?

what the hell is this poison?
when you supported with poison that can be stacked but ONLY for 2 SECONDS?
and Viper Strike for 4 SECONDS?

with out anythings that increases duration of poison then these poison is too useless

actually, bleeding is still better for this and it also longer duration than poison
yes, poison can be stacked but very short time
and it should be for 8 seconds either Poison Support and Viper Strike those without thing that increasing duration for poison

Poison still works if you know how to build for it. Also, there are ways to increase the duration of poison.
