The LG(now RA) area is not an area designed for fights over a major item like the RA, it was better when it was a side route that you needed to go to pickup the LG, or get a nice boost in health.
The RA(now LG) area is not a great area for a LG as the interesting aspect of the area is that there was a mother fucking RA down there spawning every 25 seconds.
The High YA (Now GL I think) was a great area for a YA as it created a lot of interesting prediction battles, you know someone is going to try and grab it.
The shifting of the Low YA to the mouth room sounds good on paper but it's nowhere near as interesting as battles at the MH/YA (Now just MH). The tunnel between them is way too wide as well, it could do with being made narrower.
Oh, I dunno. It just seems like no one posting any screenshots, which I thought people would do. I figured that was because they had agreed not to post any screenshots or videos until the game was going gold.
