I've smurfed before from iron to dia and here is my observation.
Iron: every round is attack round even if you're defending. They always look for the enemies and does not get the idea of running the timer even when the spike is down they will just leave it on the floor and still look for the attacking enemies.
Bronze: Same as Iron but defends a little more.
- Always look at the map, before you over rotate to another site. Example: If you see 2 people on B site mini map and there are 5 people still alive, then of course there are 3 left lurking around either they weren't scanned or they are hitting another site, watching flank and etc.
- Learn the the basic utils, and master 1 of each roles, 1 duelist, 1 ini, 1 smoke and 1 senti.
- 25% is pretty good HS% but that doesn't mean your reflex is fast enough.
- Wait for your teammates, If you peek and see 3 people rushing you and you're alone then fall back and wait for teammates to help you fight. Make it 1v1 as much as possible
- Check the MINI MAP! If you hear sounds! CHECK IT! also be aware of your footsteps, you can determine when to walk or hold shift when your near typical enemy angles. If you check the mini map there's a circular cloud around you when you're running, THAT IS HOW FAR THEY CAN HEAR YOU.
- Know your ROLE, if you're as smoker for example. Then don't be the one to first entry a site because a dead smoker = more angles to clear.
- Holding angles: STOP moving around like you have ADHD, if someone is already holding an angle for example A short, then you should be holding something else like A long, look what your teammates are holding.
- you're probably getting caught with your knife out 'cause you're always full sprinting and not aware that enemies can already hear you so again. CIRCULAR THING ON THE MINI MAP is how far they can hear you when you're running.
- Pick a spot where you're not exposed to MULTIPLE angles like you're out in the RICE fields,
- Learn to delay DEFUSE or PLANT, You don't have to take the fight in a 1v1 if you planted the bomb and they haven't tap the spike yet.
- Just ODIN your way out of BRONZE. You can easily hit hold just using ODIN.
