Turn 6 exploit?

[Lemon8or]

Reasoning: What else should the briars do apart from saving you from being devoured? Yeah they occupy space and do damage, but srsly? Their only real mechanic purpose is to save you. The Turn 9 argument doesn't count IMO.

Not all mechanics are there to save you. You can also argue the briars are there to reduce the space of the arena you have while dealing damage to people standing in it. If LoS wasn't a valid method, they'd long fix the run through for other casting skills like Slipstream, Inferno Howl, etc. You can't run through Mountain Buster or Ifrit's flame breath so I think it belongs to a different category of skills.
At the end of the day, do whatever you want OP, it's not an exploit.
