Linker is good support until the end of the game, these builds are more future content intended as all rank 7 damage classes work well with both wiz 3 and linker. So when ranks 8+ come out you might have a great damage.
If you want to go supportive forget Wiz 3, Take cryo or pyro and then cryo3 or linker 2 and chrono 3. Thauma 2 is also fine for a PvP build with Reversi and Transpose full int, warlocks skills to have something damage-wise and that’s it.
