Roboute guilliman needs a buff

I started playing about 5-6 months with ultramarines and roboute.He is good with second oath a free stra,good melee shit shoot but understandable.My problem with him is that he is 340 points.Most people will say that he is good he stands up but that is a 3+ and I dont like because its a gamble unlike the other primarch.Lion has 3 invul,morti is very though,fulgrim has a god damn speedblitz.Fulgrim and angron have the same points 340.They have more speed more T more W.like roboute angron Is a gamble too.But him is after he is killed with 16W.Lion doesnt have a stand up or a revival but has a 3 invul and -1 to wound him at 315.I hope for roboute to gain a 2+ stand up and fewer points like 310
