@Kaladesh:
personally i do not like any of those since all of them are quiet strong … in my view even to strong. i admire your ideas b.andersson, but a tank figthing with a 4 or a tank using opening fire is just to strong.
i could agree on the second but however this does favor the germans in the first who off course would be the most obvious to use a lot of tanks.
opening fire just in the first round might as well be better than opening fire the whole combat but again for a german player who is relying on its tanks this would be to strong anyways. i do not feel very comfortable about this, remember a development should regard more than one nation (which is the case with coastal bombardement which would be of use for japan us, uk and even germany when having seafights) but this heavy tank stuff would be most interesting for germany only (maybe us) so it would be more a national advantage rather than a development for all.
Well, Combined Bombardment (CB) will only be useful for US and maybe UK and Japan to small extent. Germany with an assault on UK will cost too much to have any IPC’s left to spend on development!!! So, the question is will Japan develop CB? It is not as likely as Germany will develop Heavy Tanks (HT), since Germany is likely to be economically stronger than Japan. No matter of how good HT is for Germany the CB won’t be better for US than HT, since they with HT stands a good chance to fend off any Japanese assaults in Asia with an IC and the Chinese Divisions advantage! So honestly I my opinion HT is as good as CB for US. HT is much likely better for Axis (mostly Germany) to hunt down any Allies (mostly Russian) in the continent and Africa than CB is for the Axis to launch an amphibious assault on UK or US, but cost a lot more to. CB is really crappy for the Axis and quite crappy for the Allies to, since there are much better technologies for both the Axis and the Allies. It can of cause come in handy some time, but not likely! That is the reason why I think and suggest replacing the crappy CB, since it is really not as much a strong technology than the other technologies. CB is more like a national advantage!
If one thinks that HT is too much in favor for the Axis one can replace the Rockets Tech to V2 Rockets advantage to Germany (use the old A&A Classic rule for Rocket Technology), since it is almost only Germany who will develop this technology. And replace it with HT and at the same time replace the CB with Super Destroyers!
Super Destroyers
Your destroyers are now super destroyers. Like battleships, your destroyers now can conduct bombardment during an amphibious assault at an attack roll of 3 or less. In addition your destroyers now have a movement of 3.
This one would counter the Super Submarine Technology. It would also be a strong incentive for Japan to develop, if the Japanese player has the Tokyo Express advantage!!!
One might also consider to let the Heavy Tanks to be an advantage for Germany, like this one:
Tiger Tanks
A single Tiger tank could halt the advance of a complete armoured division. These tanks were massively protected and had an extremely powerful anti-tank gun, which were more than adequate to deal with any allied armoured fighting vehicle of that time.
Every third tank you have in each combat cycle, attack or defend on a 4.
