Actually, I’ll have to disagree there. I’ll explain:
First, 1v1: You vs. the other guy. At start of match, you know exactly what you face - what weapons, their level, his core stats, his position. You can plan your strategy accordingly and leverage your weapons for max effectiveness every time. Sure, position is random, but a well-built mech will be able to handle any starting range.
Second, 2v2: This adds a ton of variables. First, let’s eliminate one and assume both mechs are fully fused. Obviously, this is rarely the case, but as time goes on the current level difference will get smaller and smaller. Now, which mech do you start with? Which one will he go for? You have 4 strategies to consider, not just one (each of your mech vs. his two) - and if you guess wrong you may be dead meat. Chances are, a mistake here - at the starting screen - will be disastrous, if not unrecoverable. Sure, you can switch mechs, but that gives your opponent the initiative - and he can switch too! All this means that a match’s result is heavily influenced by luck - he who draws the right mech wins. In 95% of cases, if you can’t get your opponent’s mech down to ~300 hp before your first one dies, your game is up. His one extra salvo he gets before he goes down will take out something like 20-30% of your health, and you’ll have to waste ammo taking him down. Even worse, I often switch mechs when I take out my enemy’s first - thus denying him the 5% damage bonus. I’ve even clutched a few matches when my second mech gets overpowered, only to have the first one reappear and deliver the coup-de-grace.
Finally, 3v3: I have only a small amount of experience here. My clan leader, L4K3, is the best resource I’m aware of for 3v3 strategy, but I’ll do my best here. Sure, 3v3 changes the variety of starting combos to 9 - but it also seriously lengthens the match and allows for recovery of mistakes. I know that L4K3 actually focused almost exclusively on 3v3 before the update, tailoring his mechs - and his strategies - to maximize his win chances. Plus, in 3v3 before the update, you always started with your first mech, meaning the luck factor was reduced to the same level as 1v1 and allowing for truly epic battles. Even with the current system, however, 3v3 is superior to 2v2 due to increased match length.
In summary, 2v2 is the match type most heavily influenced by luck. As for 1v1, luck primarily centers on starting position and RNG damage values, which are unavoidable (as well as applying to any match type). 3v3’s length allows for some truly deep strategic thinking, making it superior to 2v2. Thus stands my opinion.
