1. Right sides 3rd gem patch is an extremely vulnerable position.
2. adding to this ofc is their cliff placement in relation to where they are buliding their structures. (the cliff entrance should be flipped)
This gives left side the option (they dont have to) to go on the offensive right away and get map control. Right side does not posess this threat at all.
3. On this note, this automatically makes left sides oil far more protected. (also because the entrance to their side of the map is NOT straight onto gems.) THis gives them another huge option: they can place their warfac both at their base or at their expansion. whereas right side has to put it at their expansion to defend their intrinsic weaknesses.
4. Left has the optiion to move their conyard and control rights 3rd gem patch, whereas right side (if u you how long away the conyard movement would have to be and how vulnerable it would be to attak from left sides cliff) does NOT have this option whatsoever. (REALLY bad for allies in this case)
5. Because lefts thin icees is closer to where they are producing tanks, they have a much bigger threat in going in a sniping the conyard and all the miners than does the right side. (ride side has this threat, but its not as potent and will much likely run into defenses)
6. right (being top as well) is more vulnerable to paras because it spanws at top of map)
7. Rights ore refs for 2 out of 3 of their gold patches will have miners having to go the long way to dump ore in the other direction. Left side will have appropriatelly placed ore refs on all 3 gold patches.
8. Right does not have a chance to use lefts cliff against them. because, the distance they will have to travel to get their is too great. Whereas left can easily use rights cliff against them. This is a HUGE issue in the middle game where the approative amount of tanks on the field are there to abuse such a cliff. (this is when allies are vulnerable to attack) yet again, huge issue for allies in tihs case
