I been wondering why +- in KD doesn't allow me to be MVP. I could go 23 kills and 7 deaths and the MVP on my team will be the 19 kills and 20 deaths duelist. I just don't get it.
You expect a site anchor to always get the first kill? First of all you can only anchor a single site and you just have support util for the other site/s. 2nd, site anchors cannot rotate early and they can't die early without utilizing utils first depending on the value that it brings. Site anchors usually be the last one alive to clutch the round since they are the last one to rotate if enemy is smart enough to not commit to setups/traps especially if the site anchor is good (I'm not bragging but as I said I am usually the highest kda, more kills, less deaths).
It's because it's based on ACS, and generally, entry agents have more chances to get higher ACS if they play well than controllers/sentinels who play well. ACS kinda favors duelists and flash initiators, but you can try to get a higher ACS as a sentinel or controller by getting first kills on defense with a oneway smoke or a setup, but it's harder than getting first kills with an operator on defense.
