If my memory is not totally gone (which is possible, btw), I think a nice big number of us were on agreement that we rather like ironing the game than new planes. I'm still of that opinion and, thus, I don't think this is a bad update, especially if I bear in mind that they are just fixing the Mission Arena.
I would be betting that Misision Arena is quite complicated issue, and a major quantum leap, so I'm just glad they just throw us this bone meanwhile. And I don't want to be understood like I'm saying this is a minor update. Maybe it took too long, but I do like the net code thinghy a lot. Same the perk/numbers balancing issue. Let alone Tiger

.
All in all, I understand some frustration because of the apparent lack of relevance in new features. I just disagree on this, as I thing major things are addressed, and delay on 1.11 could be because of Mission Arena.
Happy 1.11 camper (so far) here

Cheers,
