Sometimes I think the most obvious way to balance high tech would be to allow webs at hive 2...
but u need bile bomb ALOT to counter seige attacks on a hive
I've never seen a gorge actually use bilebomb for anything but attacking solo RTs. Honestly, where there's a siege, there's turrets. Where there's turrets, there's a phase gate. Where there's a siege base with a phase gate, there's a lot of pissed off marines with guns. And a shortranged super-weak attack for a super slow and vulnerable lifeform... eeeh...
Actually, if you get a higher lifeform to take the brunt of the attack, 2 gorges can wipe out ANY base ina few seconds. In fact, we did this just yesterday on Biodome. 2 Gorges evolved in the vent at xeno, waited on an onos to attack and draw fire, then rush and biled the phase and TF. Within 7-8 seconds... poof... no pg or TF. Team came in a cleaned up.
On a side note, I new strat I'm seeing pop up is that someone immediately sves for onos from the start. Actually, in bigger games, 2 save for onos. By the time second hive comes around, you have 2 onos to take out sub bases and nodes. The marines usually don't have a fully effective counter. BUT, the onos is not a tank anymore as we all know. SO he must be used more like a fade. As hit and run when marines are present. I've seen this strat where veteran players (by that I mean good ones) horde for onos and someone else saves for hive. It wors well in the end, especially with a lerk or two. The most important thing is to wait for second hive, with DC and MC. If you onos at one hive, there's a much higher chance you won't last 2 minutes...
The problem with this strat is that ppl are so condition to say "OMG, you went onos?!? You reswhore!", so ppl feel guilty doing it. But I think it's a viable strat.
