the destructor does indeed (not work as intended) however that goes for the eradicator as well because they too try to go into close range rather than snipe their targets with their main cannon also the destructors will be facing siege problems such as armor, sustain,getting shot at from long range and the cost in comparison to artimies that are twice as effective for building destruction.
If i have a request to the devs, it woulde be. reduce the dps the maulers and athena deals they are pretty much a sucide unit and are very odd when you take a look at other units time to die and longlivity. also i rather want to see that the dreads get to apply their buffs to their units so they wont get one shoted instantly. (basicly longer combat time between units.)
1# the medics have been again abused with chessy strats like Hyperion 9-14 medics its something that is very hard to deal with. (the savager and promethius needs to be taken a look at for their uppgrades some of them is very weak and some very strong.
2# fast rush of orbital units such as avatar incursion sentry, the problem with the rush is the fact the countermersuments are to time driven as such you dont have acess to the counter units/buildings before a sudden avatar or any orbital ability is placed on your first metal node. (unless you are prepeard from the start of the game)
3#Production time and cost. the production time shoulde be taken a look at, for tier 2 units and defences. the reason is because the tier 2 units are such a game changer in general and very fast to produce, same goes for defences. these two needs to be changed in general due to the fact ashes is best played on larger maps such as medium and large however on small and tiny maps is a outproducing contest and it happens very fast and there are very small amount of time to react to it in time in order to counter.
