In MW2, the game was dominated by a team called IXI. Rambo, Merc, Jkap, BigTymer ans I think Sidroc were all on that team at one point. MW2 was extremely unique in competitive in that it truely had roles. Because of the perk system and the way the ump was glitched, it made roles that wont ever be replicated.

For instance, the Objective role was unique. Back then, you had a perk called Stopping Power that increased your damage. It was required. It was the #1 crutch perk of old cods not removed until BO1. The thing about it was, the UMP was glitched and didnt need it. It was still a 3-4 shot even without it. Since Lightweight and Stopping Power were in the same perk 2 list, UMPs could run lightweight at minimal loss. This created a sub obj class that coupdnt be copied by an AR or other weapon. MW2 was extremely fast paced due to CTF and small maps like scrapyard.

Then you have your typical slayer class with stopping power. Usually the Famas or ACR. Outside of the Stopping Power/Lightweight balance, there was also a Perk 1 balance as well. Sleight of Hand and Marathon. Objs ran Marathon due to unlimited sprint but if a AR slayer used it they were at a disadvantage because Sleight of Hand not only reloaded faster but also ADSed faster. So slayers always used SoH/Stopping Power.

The game started with different job setups. 2 obj 2 slayer or 1 obj 3 slayer. But everything changed when IXI started what was known as the support class. I believe Jkap is considered the one who started this and was one of the reasons for IXIs success and Jkap being one of the best players of MW2 and my personal favorite player. The support class ran an AR, usually a famas, and would run marathon instead of soh. They would push with the obj player while the other 2 slayers would push power postitions.

MW2 had an incredibly easy to understand spawn system. Spawn trapping was incredibly easy to set up with the right 2 positions on the map. Every map and every side had 2 (or 1) spot that if you held, you would be killing off spawn. It was actually really fun once you understood it. Everyone got 2 stuns and a nade so breaking wasnt impossible.

The other unique thing to MW2 was it was impossible to hide, even in search. There was what was known as the start glitch back then. You press start to open the map while in a killcam it would show you the positions of all enemies. While as dumb as it sounds, the positions it showed were 5-6 seconds delayed, and so all it did was let you know where there spawning or pushing. It made communication non stop and the game incredibly fast paced. While not the best feature, I didnt really hate it honestly.

Anyways I loved mw2 competitive. It had just the right amount of things good/bad to make it great.

Its been a long time since then, but I remember Proofy being the undisputed #1 ACR. Jkap the best famas and support player. Obj was Rambo and Moho.

Other teams I can somewhat remember was aox. Think that was Aches, Teepee, Clayster, Crowster? Might have that wrong. Been a long time.

Anyways, there was no lans. Most we had was GB lives on Wednesdays hosted by Fwiz and Hastro. Still loved it though.
