No need to be so sensitive, Lokust, I gave only my reason for why I thought melee combat sucked initially, I didn’t suggest that your reasons were the same. I’m sure you are a very good player :D.
Most of the real problems I have experienced with melee fighting seem to be the result of lag. I still get frustrated slashing at players who are right in my face, only to not get a hit, because in actuality they are 100ms further away from me. This can make playing at pings of over 150ms annoying, but not unplayable. Still, as I said before, timing is the key, and if you get the first hit in at the right time, you can kill your opponent pretty quickly. I find the beasts are the best for melee, as they are meant to be, and a well timed leap from a beast, will land you face to face with your opponent and allow you to wipe him out with a flurry of claws. I’ve gone 20+ kills in a row, without dying myself, several times with beasts, using only melee and low order classes, and it would be difficult to argue that you can do that mostly through luck.
My favourite ranged weapon is probably the Flux or the Repeater, because they carry so much ammo and don’t cost too much, which is great when you have to return to the base for recharging. If I am defending a base, however, I like the Balista. Wedging one of these babies behind a garrison and tower defence, means you have devastating long-range one-hit kill power on incoming grunts, while safely ensconced behind friendly defences. You can also reload without ever having to move. The marksmen’s bow, or n00bsman’s bow as I refer to it, is also good for getting your kill count up, but little use for anything else. The beast’s ranged weapons aren’t all that hot, and as I said, I prefer their melee.
My personal favourite combination, though, has to be a Predator, with Carnivore to regain health while I tear the flesh off my enemies, and Shroud to sneak me into the base. If anyone has seen Forbidden Planet, the Shrouded Predators look just like the Monsters from the ID, as they range around the Human base plucking unsuspecting victims from the ground and throwing them down dead. It’s a disturbing sight.
