As the title states, easiest way to make the game "harder" is to remove PTR. While it is nice to see what's coming up in the next year or so, PTR also kill a lot of the excitement and surprise factor when it comes to World of Warcraft. For example:
1. Dungeons/Raid encounters are tested for bugs by the player base, but at the same time it allows for said information to be posted throughout the internet and made into mods for example DBM, which anyone can download and be told what to do for a fight at the precise moment.
2. New zones, NPCs, models and quests are also spoiled even before the expansion is released. One great thing about entering a virtual world is not knowing what lies around the corner. Where entering a new zone or seeing a new mob will surprise you.
3. New gear, vanity items, mounts, pets, and models are spoiled ahead of time in still pictures where the player base usually has a "been there, done that" attitude towards everything.
I know the main reason for PTR is to kink out bugs, exploits, and polish the game so its ready for the public on release date, but why not have an internal team to test out the content in the same way and schedule its currently done to the public? If all the hard work and amazing content is being tested within the company, it makes it so there's less information being leaked. While people who rely heavily on addons to let them play the game will whine about it, isn't the big part of an MMO is the discovery and exploration of a new world? If it's all being shown to you in pictures and videos before it is released, then what is the point of spending time and money to go and do it yourself?
I know the game is getting old and stale for some, but if each expansion you had little to no knowledge of what to expect or see, except for the logo and upcoming class changes, would that make the game more enticing for you play? What's your opinion?
