sylphi soulstones only open after hitting level 90, it is completely luckbased if they appear or not and even then on average is it is like 5 per day.
How has Sarya been free, 6 stars can hardly be called free... unless you think that everyone has 20k diamonds to spend on a box hero.
5 star goram... oh my bad... well take down the total by a 100 bucks then.
And u get like 1 runestone per month after hitting a specific level.
Your team is worth a lot more then average... having 9 precious runes at level 95/96 indicates a fair amount of spending.
So yeah you did beat it, fair and square so you did show my arrogant arse I was wrong. However in the process it was very clear that a lot more then average spending was involved to get those results.
So yeah... it is not impossible if you have a high starred level 95 CS/Box heroes but if you're name is average joe that buy a monthly card and spends like 34 bucks average per month... then it is not feasible.
One of the things that is also needed is to be in a topguild that clears the raids that provide the items for your heroes.
One guildmate of mine is a free to play player. He saves his diamonds and spend it on box hero event.
You're wrong again bro, i spent 4k diamonds to get sarya 6 stars. I was lucky maybe yeah, e.g. i got two cards in one ten pull etc.
And as I said, there are alternative heroes. Not even payable without precious stones (u can put rare one) that can get it done at 95 itself. If I have some time ill upload anothsr screen.
In all, no, ch17 doesnt need to be lowered.
E.g. i could NOT complete the last 2 stages of Heroic ch17 at lv95 (others 1 starred except for one at 3 stars) But after i level up throughout lv100 and get some orange items needed it would be done (that is completing the last two and 3 starring others). Else this game would be boring and not challenging.
