In breach maps

hello.

Today it was my first attempt in doing breach map, I'm a bit worried if it will be possible at all completing all breach maps, with my build.

This league is hard and i like it. Started with scorching ray skill, did not wanted to pick blade flurry just because it's most meta thing currently. At first i sucked quite a lot against breach portals, later i got better, started to beat deathless all of them, namely those lightning ones. Then I thought I should be good in trying breach map, then i went for a cold variation and failed- time ran out and pretty early.
I can see that to beat this i should get 6 link, empower +3, 10ex+ staff and etc.
The thing is, it might actually not be that bad, but it was a COLD variation while physical and chaos supposed to be quite harder. And this worries me. Should I reroll all together and play smth even closer to the power of meta?
