Hey, I'm pretty knew to battle tech and I had a question.

What board/map size is the standard?

Me and my friend are playing a 4 v 5 at 10,000 BV, clan invasion era.

He has
>2 king crabs
>1 bane 2, upgraded gunnery
>2 wraith T1's

I have
>2 rifleman IIC's, with upgraded gunnery
>1 Phoenix Hawk II-C
>1 Atlas AS7-K

He's doing ComStar and I'm Wolf's dragoon's.

He wants to play on four map sheets instead of 2. He says two is too small and makes it so ranged Mechs don't have to move or participate in the game. I've heard some people say that you play one map sheet for four Mechs but I'm not sure what's the standard. He also said he doesn't want to have an advantage with his wraiths. I've seen other people say that larger maps favor ranged and fast Mechs too much for kiting and he'd actually have an advantage. Partially though I don't want the game to take forever more than anything which is why I'm hesitant to play on four maps.

I'm fine with playing on whatever is the standard.
