Now, I have never liked TML in this game, it has always seemed a bit too strong imo. If you get t2 same as other guys and build tmd same time they build tml you will get it done 1st, however little chance getting that t2 engy across the map to the expansion in time to save that. Now i get that the point is dont upgrade mexes unless you can defend them, but 4 mexes in base is hard to run t2, and build tmd and not also die to spam. Also, being required to make so many TMD isnt exactly cheap. Tml is expensive, but you only need 1 to do damage, where some maps to defend all your mexes you need 5 and sometimes more so none are vulnerable. Then if other team makes more tml, you need to make another 5 etc. Not to mention, in most teamgames people assist eachother with the upgrades, so theyre done faster still. Now, this has always bugged me, however i can live with it. A bit of salt when it happens but move on.
However, there is a big trend lately of people building 3+ tml to snipe through your tmd, and unless youre aeon you cant stop them. I have played in a game where i had 3 tmd vs 4 tml and they still got through to kill my t3 mex (Cybran hp op). I have seen this get to stupid levels on eco whore maps like canis and hilly where one team can make so many tml that even 10+tmd and a few shields cannot stop them, and on these maps because you have so much eco you can usually build the TML and still be comfortable ecowise. Again, i know that mass in TML is no mass somewhere else, but the counter to the TML in TMD just isnt effective enough unless youre aeon (But then you have the range issues). Usually (as there are 2 people in the 'mid' slot in team games) one guy will build a firebase that cannot get pushed through easily, while the other guy uses all his eco to spam TML. But the time you can break that firebase, usually the damage is done. Only real way to counter this is by working as a team (lmao) and having the whole team crush the base before it can deal damage, but then that only give advantage to other guys on their team who can exploit this.
IMO TMD needs a buff or TML nerf. I understand that will impact MML's effectiveness, and i get as a balancing point it is hard to do (if not close to impossible). I know that not every change will make every player happy, and if nothing is changed so be it. This is just me inputing my complaint of a trend of recent games. I have played too many games of late where this has happened and it is really starting to put me off playing.
Anyways, that's my rant done. (this was made after the 3rd game in a couple of days where i have had TML hit things 'defended' by tmd )
