"wasting time when you could be playing another match"
This seems to be the dominant, flawed philosophy. In my mind, "wasting time" means building powerplants, defenses, radars, morphing comm, etc all the stuff leading up to the later phase of the game where cool stuff happens. This is a game, and at some point you need to ask yourself what you want to spend your time doing. Consider that this game can be viewed as taking on 4 phases:
phase 1: base building, scouting, raiding, land grab. This is a long and boring phase imo unless youre raiding and/or trolling noobs. Power is always low, everything takes forever to build, cannot afford anything, teamplay is rare.
phase 2: tank rushes, shieldballs, troll comm reigns, commander assassination schemes, overrunning porc lines, doubleteaming tactics, battles for air/sea supremacy, minefields, deep penetration raids, flanks, ambushes, battles for reclaim fields, general all round awesomeness. This phase rocks about half the game's cool features and is sweet, but its usually tragically short as one team will take the upperhand here and the other team will resign.
phase 3: heavy porc fortresses, artillery barrages, scuttles and snipers, elaborate terraforms, eco building, infiltration schemes, large scale tank/bot battles and heavy air raids, tacnukes, strongest units from factories become affordable and people are either spamming or building eco/superweapons/superunits. This is like phase 1 but less lameness while preparing for the second game in phase 4. Unfortunately, this phase is often just a waste of time for half the players because one team will usually resign about halfway through it when someone's scheming works and breaks a porc line or encircles an army, or a rushed nuke or dante hits.
phase 4: nukes, singus, uberspam, massive striders and battleships, the map becomes a wasteland of razors kisses sticking out of craters and the land is infested with ultimatums. asteroids fall from the sky, construction crews desperately pile dirt to block lazor beams reflected off satellites. This is the best phase of the game. I have played it once in the last month.
some people like playing phase 1 all the time - because they cant stand playing a losing battle in a later phase. failure created a defeatist attitude and obvious weakpoints in the enemy defense go unnoticed. "oh woe is me they out eco us!!!" but you dont realize theres no defenders blocking a scuttle from hitting that singu and with it half of their base. Just bicker amongst yourself about who is the biggest noob responsible for the failure and then resign.
