This would be awesome, though i think it needs to be taken a step further than just 'weapon training'. The idea above ^ to have it in the cargo hold is totally sweet, i mean, we ALL want to go down there right!? But like i said, more than just weapons training: We should be able to pick any class, all relevevant abilities and bonus abilities, armour and weapons, a host of different arenas, what type of enemies, how many of them, your squadies and what difficulty! Imagine that!! It would kick so much ass it wouldnt be funny. It would allow you to find out what play style suits you the most without having to have to start a new campaign or switch careers. You basically get to perfect your Shepard! Great for people who don't have a ton of time to play through as all classes - though i suppose most people reading this probably have invested a ton of time into this game

- so even better for us! And it wouldnt hurt the 'cannon' or 'realism' of being a different class because its all virtual right? As far as an online mode im sure alot of people would have heaps of fun with that, but thats not me really. But to me this would be the ultimate way to keep people hooked into this game! The most important aspect (if all of this was implemented) would be the variety of arenas, as long as theres a good amount, people wouldnt get bored at all. Something this amazing is welcome to a price tag too! Bring it on!!!
