I never really use mines in general whenever I play, honestly. Not a PvP player, I will admit, but at the same time, I often times find that if I try to use the mines as intended (hidden defenses set up ahead of time), they either 1) Get detected and destroyed immediately (I would be surprised if people didn't bring stealth detectors with them; most people in MP usually have stealth detectors in their army groups from what I saw), or 2) Gets wasted on a single frigging Conscript/GI/etc. and isn't going off on the T3 Tank that I want it to go off on.
I'm not sure if there's a way for mines to only go off if there's a certain number and type of units around it. Say for EMP mines it doesn't go off unless there's 2-3 or more vehicle units in a certain radius around it. Or Genomines not going off unless there's 7-8 or more infantry units around it. Mines having a delay before priming is fine, but I don't think people are going to use them as they were intended for if they're just going to lose their mines to one infantry unit or something like that and have it do no damage (in the case of the EMP Mine).
Also...
X1Destroy probably never got his chronoshift denied by single mine placement or never lost a big chunk of his attack force to a single mine drop.
SP/Skirmish people should be denied of ability to write here.
You're denying a LOT of people then, I think. Me included. I'm not really sure how many people actually go for MP; from what I remember, people in the vanilla RA2 didn't care much for MP, but I'm not sure if that carried over to MO or not.
I don't play MP because 1) Too stressful 2) IMO kinda boring, since (based on Doomy's streams) people simply use the same old tactic over and over. Won't argue with reliable tactics, but seeing it happen a bunch of times over and over does get stale after a while. 3) SP/Skirmish is more fun. Not a fan of stressing myself out in MP; I enjoy playing Skirmish as a quick stress reliever, and I do enjoy holding the enemy horde back in SP, despite how sadistic it is at times. I've seen MP videos, and just looking at them makes my head and heart hurt. It looks so stressful...
Also, by that logic, that would mean some of the balance stuff I suggest (buff Eureka for example) would be automatically invalid strictly because I don't play PvP. To use the "buff Eureka" rhetoric as an example, if there was any evidence of Coronia players using Eureka in PvP effectively, I would've let your comment slide, but as it stands, I don't really have much reason to stop writing here. No one uses her, hell, I watched Speeder try to use her on the MO YouTube Channel, and even he was struggling to use her! And that's just one example of a unit that I want to see changed. (Speeder, you are free to interject if I'm wrong. I was going by what I saw on the WoC First Skirmish video; it looked like you were struggling to use Eureka, and then you sorta just gave up after a couple of tries. Correct me if I'm wrong.)
It's a suggestions thread, and I'm supposed to give, well, suggestions and ideas. I've warned people repeatedly that I don't play PvP. I tell people I make suggestions based on Doomy's streams, MP videos, and my own experiences. I just simply leave my thoughts and ideas here and let the devs decide. I am not trying to force the devs to go my way; would it be nice if they did? Yes. But at the same time, I know the score, and the devs probably have their own ideas as well (something that I've also said repeatedly), so I don't bother trying to be like "SPEEDER DO DIS CHANGE PLS NAO!!!1!!" or some other sh*t like that.
I try to make my suggestions as reasonable as possible, explain my reasoning to the best of my ability, then leave it up to the devs to decide. I don't want to be locked out of suggesting ideas simply because I don't play PvP; is me saying "Eureka needs a buff because she's been proven to be underperforming as a hero, and it shows in MP because every video I've seen where someone plays Coronia, no one ever bothers to train her because of her weak attack and friendly fire problems." invalid simply because I don't play PvP? Even though there's plenty of video evidence of MP players never using her? How is that fair?
