Personally, I finally had the pleasure to play as hero and I got my class character all the way to level 65.
The Good: When used correctly ( Im using a controller BTW..), you can assign your trigger buttons , In this case I set it up on my R[Top] trigger to be able to switch weapons neatly and flawlessly, because , Some situations do require melee combat with the sword, and in some instances it allows you to change to the twin machine guns and finally- with a very nice talis [The talis get some getting used to use BTW, but its very do-able.], you can easy mop-up large mobs. As an added benefit, you can use Techniques to provide support. Sadly though- there is no "Reverser" [ To revive dead players], Is there.?
The Bad: A hero - you are not allowed a Sub-class , Also If you are one of those people that just decided to hoard all those +EXP tickets, well you can at least get to level 20 , Assuming that you have that many tickets saved up.
My final two-cents:
I am starting to like the hero class alot, By contrast though- when you get really good at it and so used to it, going back to another class that we all started with feels a bit .. weird. xD
