I've reported these issues multiple times in-game now over the course of a few months, with no response or explanation from anyone about how or why they occur, if they are indeed bugs or features or if anyone even cares to fix them, who knows??? No one will probably even read this.
Issue #1: Players taking no damage: This has happened multiple times now for months, most recently 2 days ago. Myself (MCH) and a BLM where battling in Crystalline Conflict away from everyone else on the other side of the map. I used the Action Drill on him and it showed they took 0 damage. How is that possible, they have no move that allows that to happen? This happens with other classes as well, a few weeks back I as MCH used my Limit Break on another MCH and again he took 0 damage. Again that should not be possible unless a healer LB or tank is covering them.
Issue #2: Crystalline Conflict not matchmaking correctly: This happens on a daily basis ranked or casual matches, and I could give 2-3 examples of it from yesterday and another 2-3 examples if I play today. When Player A (BLM) signs up for a match and Player B (DRG) signs up for a match, if the matchmaking server assigns them to separate teams or indeed together, it will lock that option in and they will play the next 10 matches against one another or with each other, there is no reason for this in a pure random matchmaking sense. I can see no mention of this being a feature and yet it is, the net result is that if you have great players on your team well that's brilliant your going to win the next few matches comfortably, conversely if you have inexperienced players you going to lose the next few matches which in ranked matches is absolutely infuriating. I can provide screenshots from 3 days ago where I had the exact same 4 players on my team 2 matches in a row.
Issue #3: Fairness of Ranked PVP: This is more of a gripe than an issue and I have never mentioned it before, just a suggestion. Every season there are about 40-50 players ranked crystal who have won about 25 matches and then just sit there until the season ends and collect the best rewards. Meanwhile there are people in diamond and platnum with 200+ wins. Season after season now it is the same thing. How on any aspect could you consider that fair? The person who won 200+ matches had to do it with lesser experienced players than the one who won 25 matches who started there season at Gold 1 and just quickly moved there way to crystal.
A fairer alternative is that:
You win 50 matches: Gold
You win 100 matches: Platnum
You win 150 matches: Diamond
You win 200 matches: Crystal
And then whoever has the most wins going forward after that is in the top 100.
Again, I have very little faith anyone will read this and even less that anything would be done about any of it.
