The thing is nowaday getting legend is quite obvious, that leads to the thought that they should wide open everything such as "give bonus stars on winning streak at every ranks".
Back in the day its hard to reach to rank 5 Sea Giant. Ppl are encourage to play ranked mode in lower ranks for good reason of "bonus stars on winning streak" until rank 5. Even if u hit rank 10 Ogre Magi its satisfying result for a lot of us. The fact that if u play in rank 5 until getting legend u must be tryhard, play your game seriously, grind a lot and then its worth legend rank. Its not about 50% WR, u dont need that WR if u have 11 star bonus in current system.
More like a grind?! Dude... they basically give you the legend rank nowadays, what more do you want?
I reach legend on the third week of every month with off meta decks and I don't play that much. I'm not pro and I don't grind either, if I can do it, anyone else can. If anything, the legend rank should be WAY HARDER to get.
I'm not complaining tho, I get free packs and cards.
On NA, 1xxx+ legend is like diamond 5 in the old system. It is not hard to get 11 star bonus and reach legend really fast every month. Even if you drop below 1xxx and get only 10 star bonus, it is still easier than the old system to get legend, so I don't know what you are complaining about.
