This is a good point actually, i used to play another mobile game and it used to force you to watch adverts inbetween playing, with this- it takes less than ten seconds to click away the adverts
I cant agree with the comments about the pricing being 'value' however, a quick look at my offers shows 48.99 gbp (about 70 dollars) for 2 sacred shards and some trash (brews and xp bonus)... utterly ridiculous pricing to pay the price of a full game for two small chances at a decent champ.
Yes people spend on entertainment- And the monthly gem pack (9.99 a month) seems ok but i am always amazed people spend the price of several real AAA games on a simplistic mobile game and its because people pay these ridiculous prices that plarium dont make pricing more reasonable.
However, while i suspect some get into financial difficulty as a result of addiction, it is totally up to people to decide how they spend their money. Without people who do spend cash the game would not exist. Ive probably dropped £300 on cosmetic items over a period of 12 months on GW2, as i wanted to support the game and help it continue.
So whales are subsidising all of us who are ftp. Without them we would not be able to play the game
TLDR- Pop ups can be annoying but being forced to watch long adverts is more annoying to me personally.
