You put it strangely mate.
Am f2p guy needs to have ways to improve and rank up. Shall this be because he picked up luckielly 20 times in a row? Thats not ranking up sustainably.
Facing an opponent he usually looses to, painstakingly improving his builds, maxing up items, refining his approach to finally beat this dude. Yes.
As for playing top ranks (im not saying rank1 black skull, im saying sustainable top 15), as an f2p you can forget about it, luck cannot even remotly make up for that.
F2p have their playground, p2w theirs.
So yes if you are r5 or even low r1 and face me youll know the outcome directly. Shall their be such a huge luck factor affecting this?
Btw, im here talking of luck factor within a givem realm, in my case top ranks. Not such big luck that could make a r5 guy beating a r1 guy…
