Man I hate when you do Benediction on yourself. I rarely use Tetra though don't really like it that much as it's not that often that someone gets so low that it's like oh no! Benediction is always on standby for that, and if it's a DPS it's not really a huge deal, just raise them or have someone else like a summoner raise them but it's not like a tank that's taking consistent damage, usually it's more they missed an AoE and a Cure II would suffice. I was using Tetra earlier but it's not very potent for non emergency heals, instant or not. Maybe it's because I play on PS4 though, there's just not enough buttons on the cross bar for all the abilities, so Tetra has to take a back seat to other more important abilities making it harder to use as an emergency heal.
