I don’t think that’s the big problem here in that game, Tyrande at 35k compared to 59k Alex healing isn’t that big of a thing to me. Alex has always managed to get decent numbers up compared to others (I can easily get 100-150k+ depending on game length) and we also have 0 clue as to whether or not the Tyrande went one of the good builds. Tyrael took more damage than Stitches did which means more healing for Alex right off the bat.
The things that concern me more are the low XP, low assists (4 kills she was a part of out of 14) and nonexistent siege damage.
They had Tyrael shields, Probius apparently went his shielding talent. All of that adds up which I’d say was a factor in the win more. Probably a lot of poor decisions on that teams part too like suiciding to stop dragons they couldn’t stop etc.
