Don't worry, everyone is like this at first, my first thread in this forum was about KotH being pretty harsh as well, it's not as bad you think it is now. Honestly, it's just different so it requires a different mindset than the one you use on a regular DM match. The map is pretty harsh on new players as well due to the lay out and abudance of buildings which realy like dragging you into orbit.
Remember, for whatever reason, never and I repeat, NEVER go inside the globe in the middle, will save you from a lot of headaches.
