I only talked about this units because you called out a problem that already exists at other fations in a similar way. Panzerwerfer/Stuka have more durabiliy because of short shooting cycle, Calliope has more durabiliy because of more hp and armour. You can't just look at one faciton if other factions have similar mechanics.
Durability has mainly to do with armor and HP. Calliope is has much more of both.
The time a rocket launcher is firing is not the only time it vulnerable and the reason why PF fires faster is because of it sorter range and its performance when firing max range.
Again, short shooting cyle creates a similar problem. Imagine Calliope would have shooting cycle of Panzerwerfer/Stuka. It would be impossible to kill it at all.
It easy already very hard to kill it if it was firing with lower CD it would very little difference to ability to survive but it would be far better at getting wipes.
One can counter katiousha and land mattress with artillery and even a 222 will kill them. In order to kill a Calliope one needs medium tank to dive.
There is simply no comparison.
You have to take into account the stock units. If a commander fills in two spots at a faction that has two blank spots it is something different from a commander filling two spots at a faction that has three or four blank spots.
Not really you simply have to compare commander with other commanders. A commander that bring too much to the table in different areas (AI,AT) is not good for diversity of the game. A commander that Calliope and P47 loiter would be an obvious choice in most modes.
No they are not. But they have the same AT power you were talking about. You talked about infantry AT power + super heavy tank. Ranger AI is ruined with three super Bazookas, same for PFs with double Shrek. But in addition PFs have super useful and cheap Vet1 flares for self spotting (or to spot for other units) and they have lower reinforcement costs so you can afford to maintain more of them in the late game. Double Shrek PFs are as much off a problem as three Super Bazooka Rangers.
Ranger AT power is superior that PF.
Yeah, we can have the same opinion. It is possible XD
As long as we understand each other it is not even necessary to agree.
Imo it a combination of Calliope and AT loiter would simply be bad for the game because:
It would make diving vs calliope a lot harder
The commander would simply bring too much to the table making too popular and reducing diversity.
