It seems like at some point in the past couple years, you guys reworked Criticals to require you to actually land a crit on every single target. This has severely diminished the value of spells like Unicorn, and AoEs because Criticals already fall off in value due to Block, and their dependence on luck as is. I would like to suggest that at least in PVE, Criticals be reverted to how they once were on PC, for both on Console and PC (If you Critical, it criticals on all targets. But each one can block individually), This was brought to my attention when I used a Unicorn on Console, got a crit, and only healed ONE person for 1000, and the other two got knocked out because the boss hit an AoE which finished them both off even with the heal.
TL:DR I think the way Criticals work now hurt their value too much to actually be worth investing in, and due to how they work now, it makes it hard to justify heavily investing into it since Block already was a pretty major check to its strength
