Unlike other ultimates that got a cast time added, Soul Siphon is a purely defensive skill. As such it is used when under high pressure and in those situations it is absolutely crucial to be able to dodge, weapon swap and block cast unhindered and without having to worry about a skill not going off. Putting a cast time on a skill like this basically undermines it purpose of being an oh **** button, which is pretty much the only use this skill has (the duration is too short for preemptive use/to open up an offensive window).
Cast times on offensive ultimates are bad enough already, on defensive ones it is even more detrimental.
