Excalibur huh! I'm playing Volt and yes, it is very annoying when there's a big group my lightning is perfect for, but then most of them are dead before I manage to hit them!
Hmm, I wonder how long the game will keep us entertained with already two comments of people who got bored. I'm having a hard time figuring everything out to be honest, so you're right, not really new-user-friendly.
Well, then it's time to find some community to help you. Community in Warframe is really kind. Not like in other multiplayer games... but we had a friend who already knew the game a little. He helped us a lot.
Yeah, one of my friends apparently has also played the game a lot, so he offered to give us some help with the game :D
