Animation Lock: Why don't you like it?

[Pseudopsia]

A system where you're bound during animations of skills can work if it's implemented correctly.

FFXIV 1.0 was very bad example because you had to wait till your weapon skill animation completed before being able to move your character. In Ifrit fight this caused a good player to watch the log for Ifrit's combat skills, only after you know what Ifrit's combat skill was then you know if you need to run or can attack. This is not my idea of a fun combat system.

Tera bounds you during animation of skills, however you don't see anyone complaining about it. The reason why Tera's bound animation works is each class has abilities to be able to breakout of the animation such as skills to dodge, jump back, and block.

ARR is heading in direction where you can move and attack, this is similar to GW2 combat system. Without animation lock doesn't mean you need a GCD. There has to be a cool down to prevent you from spamming of attacks, especially in a game that will have PvP. Each skill can have different cooldowns such as what is done in GW2 as well as similar skills having their cool downs linked.
