I suck at mp any tips to help?

Use all your credits and buy supply and basic packs so you have revive and health packs. Use shields add ons during games. Last tip, it might be your connection. ME3 was notorious for poor networking. Andromeda seems better. Also, pay attention to where your teammates are. If they're getting objective, help. If they go down, pick them up. Worst thing I hate are players who have no revive packs and do not help out with objectives. Lastly, if you're in a lot of trouble, use a health pack. They will restore your health and shields so you will be less dependent on revive packs. Just keep practicing on bronze for now. The game will slow down after awhile.

If you're a low ranked player, stick to lower challenge levels for awhile.  It really annoys me to see level 1 characters with apex 0 in a gold match.  What are they thinking?  That I'll burn my revive and health packs to carry them?  Forget about.

Sounds like a l2p issue.

Does mp have a lot of issus because from the few matches I've played I ended up a couple of times just suddenly unable to move.
Are any of the characters better than others to stzrt with? They all seem kind of vanilla to me.

What platform are you on? Honestly having decent players with you will help. A good player can help you without degrading you or making you feel like you're not pulling your weight. Most everyone sucked at some point. I would hit up the looking for group post and make some friends and that will get you more mileage out of this game than anything else.

Ok I'll give some of these a try. I'm on a ps4.
Thanks for the tips.

I suggest selecting a map and enemy and sticking to that for a while. Change either enemy or map when you want something new. Stick to one kit as well, and stay with it a while even when you've hit level 20.

Yes I didn't realize there was special settings for the Apex missions I was thinking they were like me3 weekends. I ended sending a strike team....not sure how they work but since it let me send them I did. The match I was in had a crazy Kett with some engery bubble thing around it that seemed to send out a pulse.
So which is the easiest enemy?

Ah yeah, the Kett are the most difficult faction. Two "big mobs" there can one-shot you - the Ascendant (bubble guy) and the Fiend (big angry armored monster).

Outlaw faction is easiest to deal with. Their big mob, the Hydra, can grab you but it won't one-shot you like the others.
