One small problem with that assertion the issue of doing a full clear of beta 2 is not matter of it simply being challenging to do, the issue is that currently it's not possible at all no matter how good you are, minimum you need at least another 1 to 2 minutes.I don't think so. Insane should be a real competition even for experienced player. And if you give them 5 minutes on top it would be no longer a competition to win beta 2 with a full clear of the map
When i tried I took 7 of my strongest units, 1 bunker buster, 6 lancers, a special commander, and 2 repair trucks, and while i was able to eliminate all there units and structures, in the time limit i was timed out before I had a chance to drive down into the crater to recover my units, so like i said minimum you need at least another 1 to 2 minutes, and ideally no more than 5 minutes.
Ok so i just started this level and immediately I loose 3 units to the collective lancer VTOLs those lancer VTOLs are way way way overpowered and if they get past your air defence or if like me you don't have any air defence because you didn't have any resources to build any on Beta 01 then you have absolutely no chance of defending your self what so ever and that needs to be addressed sharpish, because that is effectively going to make the level all but impossible to complete because they are so overpowered that just 2 of those have a 100% kill rate against even heavy body tracked units and if they are coming every 2 minutes, then its not going to take them long to demolish my entire army given that even your most heavily armoured units can't survive against them.
That is completely unfair even player owned tank killer VTOLs can't kill the computes most heavily armoured units in 2 shots and if that's what there lancer VTOLs can do now i dread to think what there tank killer VTOLs can do later on.
Also I can't be sure I'll need to check but I think the spawn point for there VTOLs is also wrong, on Beta 3 the spawn point for there VTOLs is up near there base i don't think there VTOLs should be appearing at the Beta 01 spawn point on Beta 03 as far as i can remember all the collective VTOLs use use the northern spawn point on Beta 03, if the Beta 01 VTOL spawn point is used on Beta 03 then i think only cluster bombers coming to attack your base come from there, I think the lancer VTOLs always come form the northern spawn point, but like I said I'll need to load up Beta 03 on v1.10 again and double check.
Oh also i tried out doing both research and building AAA units on Beta 02 and you can do 1 or the other but you don't have enough resources to do both, so my original assertion that you need to be given more resources at the start of Beta 01 stands because you need to have your AAA units built before Beta 03 starts especially given how hugely overpowered there lancer VTOLs are currently or you are going to get demolished and even with a squad of mobile AAA to protect your ground units I'm still not sure that would enough.
