I just played my most miserable PA game. Lava world with islands, so little metal. Everyone turtled and shored up air defenses, with such little metal on the map T2 air was very difficult to maintain with this current build. So this map forced us into a T1 air battle, which was fun until flack cannons were built. I sent 600 bombers to their death on a small island that had about half a dozen flack cannons on it. All in one lump sum... Yes 600 in a beautiful formation blacking out the entire screen, gone in seconds. I immediately shut T1 Air factories off and slowly built gunships. Took about 20-40 to take the same island. The T1 vehicles and bots got some much needed buffs on the last patch, T1 air needs some love as well. Flack cannons create invisible no fly zones for T1 air, there is no getting through them. I bet if I sent 2000 bombers I would have had the same result. The flack cannons either need to be nerfed or T1 air need a buff. I am not sure which would be better.
Yeah. The T1 and T2 air balance is majorly broken right now. :-( But then again, I strongly dislike T2 units being majorly stronger than T1 units. T2 units need to be brought down inline with T1 units and turned into specialist units. But that's just my opinion.
