I think some of the mobs did need to be bigger, but some are just ridiculous ow (Chigoes for example...?)

It would be like taking a Flea in FFXI and making it the size of a taru, some mobs are just meant to be hard to see.

The mobs I think the change is good for is the likes of Puks, they always felt a lil too small for my liking, being of the Dragon family. Hopefully they make some adjustments to some mobs and not to others.
