As far as my experience although A person pls tell me if this is scuffed maths moves, I found this sustainable. Luckily, I purchased all useful unlocks by about 105 dg so had a surplus of tokens going from then to 120, and I did do daily gorago for the OSRS gold free card, to get some of the time, using the cards in my greatest potential floors. 

Other cards that I under-utilised that could help you boost xp at reduced levels were: Beguiling smoke devil - Allows skill doorways to open without fulfilling level requirements. Quite good if you are not maxed but wish to push some dg amounts. Whimsical Bunyip - a card's result is performed. In theory you can leave and re-enter dungeons activating this card and hoping to get an xp fostering effect, but I am too lazy for that.

The problems with RuneScape

Its. The material was well received, brought back some old players (such as myself) and attracted some new ones. This being said, using new players comes issue and a fresh outlook. I believe now is an excellent moment to look ahead and outline some of the biggest gripes brand new and older players have with RuneScape (MTX will not be discussed, as this is a whole topic on its own).

Server lag and capacity: As has been mentioned many times in this sub (2-3 times today at least), the servers can't handle inhabitants of over 300-400 players. In a lot of instances players opt for a ping world than a population one that is making money on runescape greater. This not only hurts the social element of RuneScape, but also breeds bitterness towards obtaining new players, as more players means less worlds to PvM in.
