I’d rather carriers got +1 attack and -1 defense (become 1/1 units) instead of up their cost.
I would also like tactical bombers to go to 10 cost, since they are 3/3s that are only 4/3 under certain circumstances.
I like bombers as they are. With the bigger map, it is much tougher to get in range of the things you really want to bomb. Plus, factory damage rules, (and tech for radar and improved factories) help to limit the effectiveness of bombers.
One prime reason we see less attacking is that we now have 2 types of infantry (infantry and mech) which are both 1/2 units.
While artillery is still around, Tanks got increased to 6 cost, making them a luxury purchase that rarely happens.If you want to see more action, reduce tank cost to 5 and make them 3/2 units instead of 3/3. (like classic)
I think part of it is the group you play with. The group I normally play in person with tends to be full of agressive but tactically sound players. We don’t turtle and if the people playing the Axis want a chance of victory they have to be very agressive. I still buy as many tanks as possible with Germany or Russia because even at 6 cost they are a good buy. Germany can still tank shock the hell out of Russia especially with Japan assisting. I have never seen(in our games) Russia get units into Africa. Especially not by transport. Axis players do their very best to sink the allied ships and a transport trying to reach Africa would be sunk by someones fighters. And frankly the way we play if Russia wants to pull units it needs to defend Russia and put them someplace else they can do so by all means. Just makes killing them that much easier. They are already hurting because Germany turn 1 should be able to make it impossible for the UK to land on their shore by taking their fleet out.
Granted tech rolls and results can cause some weird changes. I have seen Japan run totally wild because they got shipyards for example, ditto with the USA, then once the USA is at war you are in battleship and carrier hell. One game we had the USA get shipyards and supersubs in the first two turns. Then we had the USA uboat fleet that annoyed the living hell out of Japan(because their fighters couldn’t sink the subs).
Who wins often depends on who plays what nation and also on dice rolling.
