Need advice on a 2H Berserker build

I just started playing, and I'm interested in making a 2H berserker build that focuses on life leech. I wanna focus more on DPS, but yet I don't wanna be a complete glass cannon. I wanna be somewhat tanky.

I started planning out my skills, and wanna make sure if they are a good start. I only placed like the first 40 points just to see if I'm on the right track.

Here it is: https://poeplanner.com/AA4AAGEADiEAAC17jITEfuAelJ5X5FHG2FhjPfyMz_ZIXz8aPvIvajtqHhzn0iGezfKcbpf3vpd5CZY5DusJhVLZYa2Nz352rOoYUeZ3Uzs7nsWUh7QvITRBP9-yvwgkNxbpmFcAAAAAAA==

I read that Vaal Pact goes really well for berserker. But I also read that putting other life leech nodes is worthless since they can “overleech”. I already branched out to some life leech nodes near the bottom left of the tree. Those with the berserker nodes AND vaal pact, would that be overleech?
