You have a Void dash for a reason, mate. : P But I do agree, there should be a buffer of some kind between switching. (To the Operator, or back to the Warframe) Can't tell you how many times I've KYS'd because I pressed 5 too quick in a group of enemies. (They drain all the Operator's health, and they inhumanly turn their weapons back to me and drill me quick... xD)
