So you believe zig-zagging is an old method to dodge?
If using the ironsights is too hard for you then I suggest having a bit more distance to avoid aiming issues, maybe increase mouse sensitivity?
There are hitboxes and different damage types thanks to Yosh and devs with their balancing codez, that's why a marksman scoring headshots can do so well against tier 3 infantry.
Speaking of the tier infantry, that is one of those firmly rooted features of Renegade because that is how the RTS's worked. Without the tiers there is little reason for money, unless you just want to pick a playermodel and pay for your load out like in counter-strike?
You do realise how impractical that is from a visual aspect? How that would just be giving the C&C franchise the middle finger as well?
