I feel like this build favours aliens more than the last. I don't understand some of the changes as the game already favoured the aliens greatly. I feel like the alien spawn time needs to be increased. I think there needs to be a timer after aliens die (10 seconds or so) before they can respawn, even if eggs are available, or a gestation time after choosing your spawn egg.
When playing marine it feels like you never get a break and skulks just come in constant waves over and over. There is very little punishment for the alien team dying as they respawn so fast. It makes it practically impossible for the marines to push the alien start hive early in the game. Even attacking the RTs can be difficult because you need to fight off 3-4 waves of skulks.
I also don't understand not getting armour upgrades until you respawn as marine. I also feel the arms lab buildings HP is too low. It's easy for a lerk to fly into the base and pick it off then fly away, costing the marines 20 res and losing all their upgrades for the duration it's down. This along with frenzy now working has pushed the balance even more towards aliens.
I feel like with just a couple of tweaks the game would play a lot better. Simple things like hives cost increased and only 1 being able to be built at a time, along with an increase in spawn time would help to balance things out. If the game remains this way in the NS2HD tournament then I predict some matches going on for a looooong time as aliens will just keep winning over and over.
