The new meta is this:
-Rank 1s and 2s are basically reckless commandos: Nobody cares if they die at this rank, so these people play like in 1v1 ranked.
-Higher ranks: These guys stay in the base, sometimes never moving the ACU from it's original spot, and retreat if it seems like they are going to lose.
Why? Because anybody can be sniped, and usually very quickly.
Seraphim has a guy who's rank 2 who walks around carrying lots of T1 and T3 reinforcements. He uses the T1 to attack noobs quickly, and the T3 to snipe pros. This is an advanced strategy.
Similarly, a rank 4 seraphim I fought never left his base. As soon as he lost map control, he attacked with all his forces (as a distraction) and recalled.
This seems almost silly: High ranking players act like cowards and are at a huge disadvantage because they cannot use their ACU actively, lest they risk being sniped by reinforcements.
This tells me reinforcements need to be nerfed in some way or recalling needs to be improved. Honestly, it's probably the latter: Recall takes far too long when away form base and it doesn't really make any sense why it should. Recall should probably take about 20-30 seconds and be the same amount regardless of where you recall from.
Also, auto recall might not be a bad idea, but it should have some kind of penalty.
Also, having a lot of small maps where utilizing the ACU offensively is essentially but where being sniped is really easy might not be the best idea.
