There are a huge number of variables to consider in s44 combat.
tactically, units are small and massively effected by terrain, both for LoS and more importantly grenade range; attacking downhill is a massive advantage.
ranges are large in proportion of movespeed, and once combat begins units are pinned in position. poor initial positioning results in massive losses, requring constant adjustment of disposition.
combined arms are grossly important. mortars will massacre their cost, but are also vunreble to attack and invisible snipers.
urgh i cba to go on. tl;dr - BA combat is, on the surface, fairly simple, mostly focusing upon the relationship between t1 vehicles, which all have fairly similar properties.
s44 combat is a crossly complicated mess of variables, with different unit types in each teir having wildly different abilities and applications; the ammunition resource demands a balance between instant firepower- laying lots of damage fast for pinning and opening a breach- and conservation, so you can reload vital units, such as tanks.
there is just no way of comparing it to the simplicity of *A
*A competetive play has depth because people are very good at it, much like starcraft.
even unskilled s44 players are coping with a great deal more depth of gameplay (and not neceserrily coping very well).
the requirement for reflex is, however, much less; most units do not require intimate micromanagement, so a lower APM is required.
I respectfully disagree with the confidence with which you lay down your opinion.
For the sake of this discussion ill leave out other TA mods and write of BA only.
The unit variety in BA is staggering,a tech progression with several levels.Sea units,land units,hovers,air units turrets of all sorts,jamming radar,los,sonar...
A very complex economy that only seems simple in retrospect after you have understood it completely.
Saying it's mostly about t1 vehicles is not really a serious argument at all.
The fact 1v1 does not see a lot of this variety i just cause of a lack of proper maps that exploit the different advantages and disadvantages of certain units.
It is easy to create a 1v1 map,for example,that would make players tech up in most cases when playing a 1v1 but we do not have such maps hence T2 is only left for crowded team games which also exhibit part of the game's complexity...
Although my experience with S44 is not huge,I am sure it is also very deep but I sure don't feel easy about stating on of them is more "deep" than the other or that one requires more thought..
It's not your duty or role to be unbiased but your post did not seem like a simple fan reply...
