Bit the bullet and got PS+ sub for 1 month to try out the multiplayer part of Ghost of Tsushima: Legend. And, I gotta say I find it pretty fun. I'm playing primarily as a Ronin class, which is basically the closest you can have to a healer in that mode, but once you build him up with some abilities he's really damn good at support. Plus, he's still a sneaking assassin stabby stabby guy, so it's like they mooshed a white mage and a rogue together, so...kind of best of both worlds for me really xD
The survival mode is where Ronin shines, as it's all about endurance and ...well..surviving, so his healing abilities are incredibly useful. It reminds me of the multiplayer for ME 3 to an extent, at least the survival part. Waves upon waves attacking various defensive points you have to protect, though losing them in GoT will cause you to suffer max health penalties, which I don't recall being a thing in ME 3 multi.
In the story missions for Legends, it's less useful, but still helpful, as what you are doing in the story missions can change. Part 1 of a 3 part story might be sneaky sneaky, but then the final mission is a "defend this node" kind of fight, where sneaky just doesn't cut it, so heals would be nice. It's not that difficult to just solo th estory missions, as they are relatively doable solo, if you know what you are doing.
The quality of matchups for the survival quickplay is pretty standard. Your typical menagerie of competent players and bumbling fools, but for the most part, my teams have been good enough to win every match. I think I've only lost maybe...3 survival missions overall? And I'm currently running on Silver difficulty regularly. This might be because I'm playing support, and know what I'm doing, so I'm able to shore up the lack of skill on the other members' side, but, frankly they generally know what they are doing. Plus they are all very polite to the white mage and bow at me whenever I use my healing incense to top up their health, so that's always a plus.
But yeah, so far I'm enjoying it a lot, and my wife enjoys watching me run around playing Ninja White Mage in multiplayer. Not sure how long it will hold my interest, but I played it all day yesterday basically so....it's enjoyable so far.
