Some useful advise here. Another problem I have is that I rarely see the enemy,
then sprint to next cover and so on, but eventually get killed most of the time with only one shot. I think the game suits campers or defenders, as attackers have to take more risk.
They do, but I personally prefer choosing the attacker in most maps than defender simply because I like the challenge and my personal tactics suit that role.
The game may first appear to favour campers, but if you camp, you'll quickly find out that it doesn't. Stay in one spot for too long and someone will eventually find you & kill you from behind..... and will keep killing you until you find another place to hide.
This game doesn't work the same was as the other common FPS's out there. In those games, you can run out in the open, take a couple of hits, then hide somewhere & wait until your health regenerates, or someone will come along and toss you a medpack or simply heal you.
In RO2, if you run out in the open and get hit.... you will die. You may get wounded and find a place to hide to bandage your wound so you don't bleed out & die, but usually the second hit will take you out afterwards..... in other words, there is no health regeneration and there is nobody to come and save you.
They just sit there and wait for the attacker to appear at some point which he must do.
Yup..... but the plus side for the attacker is that you can approach the objective/enemy from any angle/direction you please (Head straight at them, flank them, smoke them out & get up close and personal, toss grenades, etc.) while the downside for the defenders is that if they want to properly hold the objective, they're confined in the objective and boxed in.... if they're wiped out by arty or a good offence, it'll be very difficult for them to flush you out and re-take the objective..... or worse, you capture the objective and then it's locked out, which means they can't take it back and have to fall back to the next objective while you rush towards it.
If I rarely spot anyone how can they see me so easily. Its is very hard to get a kill first time against a sprinting unit. Maybe I should look at map more often when there is a commander.
With sprinting targets, you need to learn the distance to lead the target based on the distance and their speed..... eventually you can master it.
As for people spotting you and taking you out, those people may just know the map a lot better than you and know that you're in a common spot your team uses..... they could have also seen the muzzle flash from your weapon as you fired..... or they just saw your head poking out. As I said above, don't stay in one spot for too long. Get a couple of kills and then move to a different location, otherwise the enemy will get wise to what you're doing and come at you in a direction you won't see coming.
As for the bots snap-shooting you in one hit.... that's just how they work and no matter how fast you think your are, or how good you think you are, they can often get the upper hand and appear to head shot you with a hip-shot while they're back is turned.... they need a bit of tweaking in this area, as it happens to everybody & has nothing to do with you being older and having slower reflexes, etc.
They turned around & shot you faster than your ping could display, which is why it looks like they killed you before they turned around & aimed...... in some areas, the bots are a bit faster than the average human & can be a bit annoying.
