The longer you play, the more appreciation you have for some game modes. Another thing that really helps the enjoyment is having communicative and trust worthy team mates. I love using tags as bait until all's clear.... but I hate it when my n00bmates run way out in the open to collect tags that are surely going to get them killed. It happens all the time on that big bridge in Sanctuary and just about everywhere in Abandoned. Even if your team doesn't know what they're doing, so long as you keep the lines of communication open you'll have fun regardless... Also, Search & Destroy is a riot on the two new maps that just dropped. You can have some long games on Sanctuary.
My randomly assigned gamer tag is PerpetualPack4. Don't be afraid to invite me or nothin'.
