Probably the best addition CODM has ever added. It's the next best thing to a banning system. It filters out the good from the meta abusers, little timmies and noobs, and removes one of the two overarching antagonists of the current CODM meta.
MARTYRDOM
But yeah, just keep a daunted class or two to counter the man o war thermite.
What League Play does is basically, it grants you the exact conditions banning and limitations that pro and esports competition matchups have.
Minus the gun and attachment bans, which i think is intentional, to add variety and for analyzing the reviews and criticisms, since this is a brand new addition to the game.
The only scorestreaks allowed are hunter killer, predator missile and emp systems.
All utility and support operator skills are banned.
No wildcards.
Hardpoint, SnD and Control are the only game modes.
It also limits your colored perks, so quick fix, vulture is removed, hardline is as well.
The biggest gripe i have is how people are quitting, possibly out of rage, or just that they aren't used to this level of competitiveness, and the matches are long.
Overall my experience is a 7/10. I love the intense matchups, and it's good, since it's pure gun skill. It rewards good players like you and me.
Tip:
Dead Silence, Survival Training and Tactical Mask are the only useful blue perks, preferably you should choose tactical mask/Survival Training for respawns, and DS for SnD, but they could work for respawns.
Scorestreaks are impossible to unlock in SnD, so don't worry if when you play and there are no scorestreaks in your loadout.
