War upgrade task cannot do, blocks others

3000 points task unable to do blocks other high values! So I getting all tasks at less than 2000 points! I did get a list one after the other at 2400- 3600 then it changed again back to 1440 - 1600! I am lvl 99 and with them numbers continues I liable to win no prizes or be demoted as the game is in control. I use to be able to do certain tactics to get better tasks. But not working for me now! Am like a slave to a bot! That is stubborn, now if impossibly tasks at 3000 points was removed once when they get expensive on keys to do war upgrades as now it cost me 454 gold keys to upgrade 1 card. I can only do that task every 6 weeks, as that how long it takes to collect them for the required numbers. When it drops that task, then as I not able to do it I am penalised with very low values of 1440 - 1600 and occasional high one! Been at lvl 99 is crippling me and I get pushed out of a good prizes almost the whole season, because of impossible task, one week when I was close to getting the keys I worked hard to get the rest, I tried to leave it till I not get it again before I used up my task so could get a better placed! It worked and I did get the top 6 not first but 5th!, I made do. So if made it if not going to remove it, as some players say they only get it twice a year! That would suit me fine and it not **bleep** my com!
