Many players and mods have been complaining and adverting me about my lags... Ok, I know most of the time my bad 3G signal has the fault, but yesterday I was lagging even with high-velocity wifi! Conclusion: sometimes, lag is server's fault too...
I know that developers are always working on it - but at least some other players and mods could stop complaining about laggy players... As I already stated before on other threads and posts, when you face a laggy opponent, don't waste your bullets and your precious time chasing him after you are sure that you landed 2 bullets on his/her craft! Go for the next target, and eventually (possibly many seconds later) the laggy player will be registered as brought down by that 2 bullets of yours. Acting so, you won't be solving the lag problem, but at least you will be minimizing it a lot. And remember: the lag doesn't bring only benefits to the laggy player (as turning him sort of "unbeatable"); it brings serious problems to him too! (example: when lagging, your bombs and kills takes a long while to be registered by the server too!).
Of course that there are other bad collateral effects caused by laggy players, but after all, laggy players are players too, and they have paid for the game as well, and have the right to play. It's a matter of the developers find a way to "segregate" laggy players in specific sessions, or even preventing them to play at all - but if this day come, I hope that developers will make sure that the lag is ONLY an user-end-of-the-connection fault, because as I already stated before, it is not always the case...
