The Targeting System Is Failing on PS4

[Felis]

It's true, sometimes it's honestly better to use the extremely slow controller trackpad to click on enemies. At least it's somewhat easier to select party members, you just gotta cycle through the party list as fast as possible.

But when i'm doing solo fates and i want to toss a heal on someone else who's by themselves, it won't let me target them with tab targeting. No matter what i do.

Change to a target filter that allow you to taget players without targeting enemies.
Also the R2+L1 or L2+R1 tab-targeting ignore the target filter and only target enemies.

Also to OP: There is no difference in the target system with a controller between PC, PS3 and PS4. Maybe you configured it on the PS3 differently than on the PS4.
