Also I see a reason why you are losing so much.. so take a huge breath, swallow ya pride and read the following line:
MT does NOT counter SC ever, SC counters MT.
There... you are right.. You ARE wasting res with MT there simply because you are using the opposite of the counter. 'But it works' only applies if the aliens are to stupid to realise your huge mistake and can't use SC correct. Lets make a list shall we...

* MT is useless versus SC. INrange of a SC MT does not work.
* MT is 35 res delaying Armor (which DOES work, armor2 even when combined with meds)
* MT is making you not use your obs for a few times disabling scan AND phasetech.
* SC has no defensive qualities when you can making it hard for kharaa to counter. PUSH. PGs help alot in this situation. They lack DC to retake a position and they lack MC to rush towards one. Scan nullifies the benifits of cloak, armor and welders help versus focus.
* drop welders. armor + welders is far better spend then 35 res on MT.
* the LONGER the game takes the more time they can place SC, the less MT is affective. Already set you down at the beginning, not it drags the game even more down.
* if they place OCs under cloak MT aint gona help, armor makes all the difference.
* TEAMS.. go in groups. teams even with less armor then prefered are a good counter since the kharaa decloak when attacked. if ya teammates helps shooting...
The ONLY reason why MT works is not because its a counter, its because you can play DESPITE of it. Kharaa are simply crap. Why?
* they probably do not SC important presure points and probably do not bother to place SCs correct at all. Or expand the network when possible.
* they do not focus own you to hell since you got MT instead armor
* they do not secure hives even though you lack the ups to take them.
* they don't use SOF well, since it does not matter if you have MT if they see the rine movements aswell.
A good gorge can lay a SC network if he is gona place 3 SCs anyway which totally covers the kharaa starters territory. The one corridor not under cloak aint gona help you if the chokepoints are all cloacked way before you reach it.
really... armor, speed, scan, PUSH.. those are all counters and help alot more then MT. Even a TF works better then MT when they got cloak.. Be glad if they got SC, its mistake one.. now try to force them to make more and tech up HA fast and they'll never get over it.
