If you have the right strategy and enough knowledge of the facs and units, every situation can be exploited to your own advantage.
I understood the game that way; that if you know the macro, it does help a lot to gain some micro, while it's not too important, although it's helping - and then get a lot of knowledge about the facs/units. How to counter what and be creative with exploiting.
And for me as lob, this is my biggest weakness: I don't know enough to react fast enough (not even manually, but also in my head: How to counter react) and my exploits are kinda buggy.
TLTR: Jumpers have advantages, which others facs don't and vice versa. No drama. All fine.
All about training ... and this is the thing: Youtube videos from Godde and Shadowfury333 do help a lot. But those are limited. So it would be really useful to have an filter option in the replay list (or better a replay list for all games, not for certain players), where you can filter according to more parameters. Like 1v1, 2v2, 3v3 etc. also which was the starting fac of at least one participant.
Eg. you want to know more about jumpers: Search for 3v3, jumpers, some random top player and see what you get. There you are, being able to have a beer/coffee and a relaxed game analysis.
