Any Wraith that pops her tactical and does NOT run back towards her team deserves to die. Both tacticals are bad at escaping an actively pursuing opponent regardless of any movement abilities they have. The tacticals of Loba and Wraith are about equal with situational advantages to both.
Her ability was supposed to be an escape ability so they've taken away it's intended use but that can't be helped.
The Revenant Ult I can't comment on. I personally swear they buffed the shadows health as they were pretty easily dealt with before. I might just be a sore loser here.
Comparing Wraith's Ult to Octane's is ridiculous. The stronger the Ult the longer the Cool down should be and the inverse should apply for weaker Ults. The Jump pad is viewed as a weak Ult while the Portal is considered top tier. The longer cool down feels justified though I dont think it matters much.
Rampart's abilities are strong in theory but weak in practice. Random team mates will push fights away from your walls and her Ultimate has more weaknesses than strengths. Weak Ult = short cool downs to me. I'd honestly shorten Shiela's cool down more given how little value it adds.
