Considering he already has dakki, he already shouldn't be struggling with any wind content. Uriel+Dakki is plenty enough to carry against any wind content, without having to further miracle ticket for that element. For the longest time ever, I didn't have svarog, and I still never had a single problem against any wind content whatsoever. If he wants to go down making fire his focus, then sure go for svarog then, but it's not like he's currently handicapped in that element or anything. If he's missed a lot of the past events, then his grid might still be lacking in the end though making it a bigger handicap than anything line-up wise.
Honestly his wind looks pretty damn stacked, and might be more stacked than anything he forms in fire. With a lineup like that in wind, I'd focus on maxing out everything in that first, grids-wise.
