Nightingale vs shroud

What do you guys think of shroud vs nightingale, I feel like with all the healing powers banished have the shroud are a bit overpowered, making UNSC siege impossible, ive been using shrouds a lot early to mid game, go with infantry and arbiter, smart option would be Kodiaks /vehicles for enemy, but shrouds almost block everything, makes me feel a little cheesy, but hey i never see them get used often. (Honestly could be that Enforcers are too strong too)

Siege vs UNSC is annoying as nightingales do group heal and smoke, but lack any blocking of projectiles, where if someone is sieging the -Yoink- out of you the usually send detect units.

Edit: Wolverines should shoot more rockets 3 shrouds can make like 3 wolverines completely useless.
