First: Thank you everyone

I dind't think that someone would even read my post honestly.
I spent about 30 mins to 1 hour on mp tonight to test it before posting my opinion here. Maybe it will get better with more practice but there are many obstacles we have to overcome first.
For example like AbyssalDragon86 said: it's a problem to host servers because players often get timeouts or (like me) can't even join a Server because of the distance. The old community had players all over the world and i guess it would be great for all of us to be able to play together without taking the country we live in into consideration. That's just my opinion.
Second: Many weapons like for example the Tek Bow or the Plasma Rifle are kinda strange compared to the original weapons in the MP from Turok 2. The Tek Bow shoots too fast in my opinion and the Plasma Rifle shoots to slow and doesn't make enough damage. The Plasma Rifle was the ultimative weapon in the old MP because it made -100 HP damage (except when you hit the weapon) and now it seems like it makes about -50 HP damage? And it explodes more when it hits something. That may be a positive effect when you're not able to hit the enemy dircetly but on the other side it's a pity that is so weak now. The Grenade Launcher was similar to the Plasma Rifle when the grenades hit an enemy directly they made a -100 HP damage aswell but in the new MP it seems like it makes about -50 HP damage too. I don't know but if I get hit by a grenade I would die.
There are other weapons aswell that changed alot but I guess it's enough for now

Third: Thank you for the hint Gazer!
the problem is, that I don't play T2 often so I'll forget on which key I put the weapons I need ^^'
I'll just wait for an update where the bug with the auto-switch new weapon option gets fixed hopefully
And until then I'll try not to pick up weapons while fighting. Or just won't play.
I'm looking forward to an update
P.S. Dinomite maybe you'll get to like the game once they fixed and changed all these things

did you already buy the remastered version of T2 btw?
