I just played a game on a Tier 6 Furious against bots in operation Aegis. In the game my rocket squadron was slaughtered by the first wave of 2 battleships, 1 cruiser and 2 destroyers all tier 5 within 10 seconds, allowing me to strike once. My bombers were then slaughterred by the second wave of furutaka and aobas while turning around after slingshotting. The third wave had their AA disabled so I did the majority of my damage there. During the last wave, I lost 2 of my 4 torpedo bombers to a lone Fuso. The Fuso that is notorious to have one of the worst anti air in tier 6. Before the new patch, I had run the same operation with the Furious and I had at least managed to get 3 strikes off on normal enemies and have my planes returned to me, or 3 strikes with no planes returning if I was forced to strike a defensive AA cruiser.
This change really hits all the tier 6 carriers hard, because unlike the tier 8 and 10 carriers, none of the tier 6 carriers have the reserves to withstand this AA buff. They also don't have the damage to justify the loss of my aircraft. Each Furious Torpedo does 3k damage, I'm not regenerating planes every 10 seconds, it's a heavy loss each time one of them goes down.
I only play operations in this game. Carriers are my favourite ships. I can no longer play carriers without dragging the rest of the team down.
If anyone says I'm crap or that I'm losing all my planes because I don't know how to play carriers, then go into that operation and try it out yourself in a Furious.
