Just for you Shane!Definitely a good update.
I find the new Temple Trekking lots of fun. Been able to select what kind of reward you want makes it worthwhile, and seeing your companions level is rewarding in its own way. Some of the NPCs are much harder to level than others, which makes the mini-game more challenging. It took me all day to get the full set of Constructors Outfit, and I must say it is pretty sexy. It will take me a few more days to finish getting all the other rewards available.
The graphics changes to the whole swamp area nice. The green fog is a little weird but it fits. The ghasts are scarier than before. IMO the place looks creepier than Draynor, so maybe it will keep some adventurers away! The farming area NE of Canifis is glitched in HD, and I heard there was a problem with the shorcut getting to barrows (which should be getting fixed soon).
I can't wait to see all of Runescape updated with the new graphics. The changes of all the trees around the Varrock, Falador, and Lumbridge give the place a different feel, its like playing a different game. I remember questing around this areas before, and I wish the trees where that nice back then. If you lower your camera down while you run in this areas it makes you feel like you are actually inside the game.
And last, I think the best part of this update is the ability to bring summons into the GE. I was sick of having to dismiss my familiar every time I came into the area. Specially if I was just getting new supplies I had ran out of in my bank. The fact that they pause your familiars timer is a nice addition to it. I wish they would of done this before, but I am not going to complain. It is finally done!
