As the new map won't be updated for 1.28, I suggest to remove some of the combos that were removed in the new patch.
The two most broken combos that were removed were rearm + phantasm and rearm + x-mark. A simple ban on these two combos would go a long ways.
tl;dr : Ban rearm + phantasm and ban rearm + x mark
Please don't spam the topic with other combos that you think are overpowered that were NOT removed from the newest patch
Full changelog from the first version of the new map:
Spoiler!
Primary changes Checkout config.lod file which appears after launching map in the WC3 root directory. You can use it to setup static hotkey per every slot. More info at config.dota description. Note that some features are still unavailable, even if included into config. More to come later. All picked skills will now appear in the order you pick them. The order of spells won't change, even when buying aghanims, or refreshing spells with Rearm, or learning new spells. This only affects your own hero - skill-layout on your allies' PCs may be different. If you don't want this feature, go into config.lod file, which appears after the very first launch of the map, and change the option StaticSkillsLayout from true to false You can now see your allies' spells, their spells' levels and cooldowns by clicking on their hero.

Rearm no longer stacks with X Marks the Spot, Teleportation, Sanity's Eclipse and Phantasm (now only pickable in -rc rearmcombos mode)
As teleportation and Sanity's eclipse are not as broken and widely picked as x-marks and phantasm, they can be dealt with later if needed (they both have items that can stop them)
I definitely support this, especially because they were disallowed in the update (even though we can't play that verison). One question though, is it only Phantasm that's banned with Rearm, or are we including things like Metamorph + Naga Mirror Image + Rearm?
Edit: In the changelog it seems it's only Phantasm, which answers the question I guess.
