I would not take it as far as a “guarantee” when it comes to mobile players being less capable compared to PC players. Sure, PC players can spam and kill a lot of people without lifting a finger, but that doesn’t mean that they totally outnumber mobile players in combat games.
I have to lift 2 fingers to get 11 cps on cubecraft, due to the no double clicking rule.
I play on mobile and I beat guys who could spam me without hesitation.
Cps is far from the most important skill in pvp. Aim and movement are where it's at. Both are fields where mobile poses little to no disadvantage.
There is something in Minecraft (or anything that has to do with attacking other people) called strategy and it is used to take down the opponent. One of the things that make me better than 95% of all Minecraft players are bows. I’ve used them in Eggwars so much that I forgot the physics in the real game for bows (yes there is a difference, try it if you don’t believe me). I also spleef people and tnt bomb them and do pretty much any strategy you can think of.
Success using this kind of gameplay takes a opponent who doesn't see it coming. A decent player will just place 4 blocks and your arrows are useless.
It just takes practice on mobile to get better, and anyone could do what I do in the game, but most aren’t willing to give mobile a try, and I can’t blame them considering it does have its downsides.
It takes practice on every platform to be good.
But next time you see someone playing on mobile, DO NOT UNDERESTIMATE THEM, or you might just find yourself with a “You Died” screen in front of your face.
You should never underestimate any opponent. Mobile players tend to be younger and often have less knowledge about the game, and are therefore seen as worse in general than pc or console players.
The main skills to learn are sprint resetting and strafing, combining those you can win fights with only one or two cps, providing your timing is good.
