of first of all the smac guns are not doubleing as repair and hangers so dont assume things secondly you didnt hear what i said the covenat can jump any where in a grav well meaning they can jump behind the mac guns we probally have to increase the size of grave wells so they can wait out side a kill zone also yea they are powerful but you also forget mac didnt always hit there targets and sometimes they will shoot the same target so the whole overpowering thing is not an accurate stament
1: SMAC platforms ARE doubling as hangars, I know that much for sure. I just assumed they would double as repair stations since they could dock frigates, and destroyers, and would have full repair crews onboard.
2: Well if the player was using SMACs properly, the SMAC platforms would be as close to the planet as possible, IMPOSSIBLE to jump behind them unless you can jump INSIDE the planet. If the player leaves the SMAC's flanks exposed, that's their problem and has nothing to do with the mod.
3: SMAC platforms almost allways hit their targets, the only exception being at extreme ranges. But due to the fact that a SMAC round traveled almost the speed of light, it'd be impossible to dodge it at close-medium range, which is where most engagements would take place in Sins. Also, it's the players choice to position SMAC platforms properly so they don't all target the same unit, so again that has nothing to do with the mod.
In the end, the cluster idea is just pointless, and wouldn't work properly as something would have to be removed. You can't give a player three fully operational SMACs for the price of one, and you can't jack up the price cuz then it's too hard to properly defend yoru planet. That means you'd have to dumb down the cluster to be as strong as a single SMAC, which is just stupid. Just make it singular and let the players build them, it works fine for every other mod, it'd work fine here.
