Man no. I know a guy who has 25 etheric already because he plays the modes that give you guaranteed etheric. He's not on everyday, he just plays 2 modes on each character when he can. And trials on weekends. It doesn't take that much. No need to add a way to buy it because that opens up the market for exploits and for people to have 50/100 and not even need them like shards. The point is to be cognizant of how you use it unlike shards & energy these days. There's a reason it's so scarce. If it were too easy to obtain the 35 arena would be a cakewalk. 34 already is. No need to keep making a grind game easier for casuals man. Get over it please.
