Odessen:
If having a battle mod prevents stealthing then it should also prevent some other skills such as entrench, sorc immunity bubble, merc responsive safeguards. Entrench is the biggest one though it is impossible to stop a sniper from killing a node due to this. No battle ground should favor a class like that so heavily.
Hypergate: The biggest problem with hypergate that I have seen is the fact that kills don't seem to clear at the end of the round if the team has no pylon. example, We were behind one round so the next one we prevented the other team from getting a pylon but in doing so they got a lot of kills because we just kept throwing bodies at it to interrupt, This let us catch up with the score at the end of the round with the opposing team at about 300 with us about 20 points behind still. So the next round we thought okay that is a more manageable gap so we didn't go to interrupt them. As soon as they got the pylon they went from 300 to 580+. It seems to me the only way this happens is if the kills from the previous round didn't clear and possibly even gets multiplied somehow.
