Disruption matrix: the real reason it's too strong
The issue isn't the damage(which the most recent patch reduced). The issue is that with it's enormous AoE and scaling abilty diable duration, it fairly quickly is going to prevent the entire enemy fleet from using abilities for 8-14 seconds. Which means other factions can't use the tools they ordinarily use to defend against AoE damage against Disruption Matrix's damage(Advent in particularly is hard hit as all their counters to AoE damage are channels that will be interrupted even if they were cast before disruption matrix is activated).
The real proverbial kick in the nads though is the synergy with other AoE damage. Disruption matrix's damage alone is managable, but throw in an EMP charge from the Dunov or even simply add ina sufficiently mature TEC fleet's weapon damage and that's a ton of damage that the enemy is completely helpless to defend against. The worst case is when combined with a Marza level 6 ability. The enemy can't defend against marza with aoe mitigation abilities and worse yet they can't even interrupt the Marza(unless they happen to be Vasari and have a lucky Kortul handy). With easily 11-14 seconds of the marza ult untterruptible, combined with disrution matrix's damage, that's easily 2500-3000 damage to the entire enemy fleet which the opponent can't really respond to and mitigate with aoe-counters in any way.
Also it just creates a bad game situation for a strategy game: If the opponent uses Disruption matrix intelligently(when the opponent doesn't already have any defensive busts such as repair cloud or another TLT's group shield active), there's really no counter-play to this tactic. The ability quite literally disables pretty much all of the enemy's counter-play tools. Things without counters in a RTS are bad for the game even when they are technically balanced.
Honestly I think one of four things have to be done:
1). Have Disruption Matrix only disable the abilities of frigates BUT Have it increase the antimatter cost of abilities used by capital-ships by 100%(perhaps a 50% cooldown increase as well). It will almost have the same effect on capital ships(they will use abilities sparingly during the duration), but they at least have the option to cast that one key defense/interrupt they judge to be so necessary it's worth the drastically increased cost.
2). Have Disruption Matrix also disable the ability use of allied ships as well as enemy ships. The real problem is the synergy of disruption matrix with other aoE damage abilities. Turn Disruption Matrix into an ability dead-zone for both sides solves this. It would still be in the TEC's favor due tot he AoE damage, TEC's naturally long cooldowns on many cap ship abilities(Disruption matrix could be used once the TEC player has all their key cap-ship abilities on cooldown already), and the fact that TEC doesn't have many channels they have to worry about interrupting(whereas against advent opponents they are likely to at the very least interrupt any instances of guardian shield projection.
3). Have the ability disable be a static 5 seconds and only the damage over time duration scales to ranks. 5 Seconds is managable- there's only so much the TEC can do in that period(with marza 3/4 of the ult would still be interruptable). It's really just the higher ranks that pose a problem.
4). Give all factions counters. This option requires no enrf but is a great deal more work. All factions would need some form of defense against AoE not negated by ability-use prevention.
Either way, With any of these changes I could see the damage enrf revoked. The damage was never really the problem IMO. Anyway, post your own thoughts on this ability.
