Well my computer is finally fixed thank god, so I decided to play it tonight. It was quite fun, we had one weird bug appear in a match where we started 3v3 in lobby, then 2 left as the counter started making it 2v2. But ingame we ended up 3v1 + 2 AI while the guy that was supposed to be on team 2 got with team 1 and could see both bases which was odd (alliances messed up). And as mentioned above, being able to open the inventory without selecting your hero would be nice as the numpad 0 is far from the buttons i use to play sc it kind of gets annoying click shop, buy, open inventory, put item in right slot, sell item, click shop, open etc. Other than that it was a great map, perhaps a bit fast as I'm used to the old battle tanks which could last for up to an hour.
Definetely the most polished custom map I've played on sc2 so far.
The repair thing after buying hit point items is deliberate, and actually triggered. If this didn't occur, you could buy a +400hp item and simply equip/unequip it to heal yourself infinitely.
To counter that, you could make it so it damages your health by an equal amount if you unequip it unless it would kill you? Hmm perhaps that would get some exploits like equip/unequip spamming in combat so you never die... must be possible to trigger a failsafe for it.
Since my computer has been broke for 2 weeks I haven't been able to try this map, but does the shield regenerate while fighting or only out of combat? I remember seeing a game (is it even standard?) where shields only regenerate when you are not fighting. It's kind of hard to give an opinion on this but if you do have them regenerate in combat and they are OP, perhaps considering to stop combat regeneration might make them a bit more balanced rather than having to ditch them totally?
