I also enjoy reading this thread, thought I would recap a bit, and add my own suggestion to the list:
Ideas so far: (some have been implemented in game already)
being able to customize your cast action
being able to customize your bobber
a new fishing pole
a cool new trinket.
28 or 32 slot fishing bag / tackle box
an achievement for unique fishing poles collected
a 'killable' dark herring
Something that emulates active trolling with a lure.
Different lures at different levels
specific lures for specific fish.
Accuracy tied to skill level.
Fishing boat!!
fish from my sea turtle mount
an option on the sound tab to make other fishermen's bobber silent
A fisherman's vest: ( w/ sockets & pockets )
a custom sound for your bobber
additional fishing dailies
I like most of these ideas, some are actually quite cool, a trout boat mount, useable only on water.
A vest with sockets and pockets - awesome! the different lures on the vest adding to certain types of fish, or
your fishing skill in general... things along this line.
A specific bag for all these cool new items - needed.
My own ideas to improve fishing include cooking skill as well. I think you will also like this idea. Fish food & Chum. To be used at the water side to create your own fishing pool.
I have not worked out all the details, so before it gets beat up; think on how you could make it work!
What I have thought about on this so far is that it would be skill based and recipe driven. Recipes acquired thru the typical game mechanics; quests, drops and (of course) fish-able loot. Each recipe would require it’s own mats; different types of fish, spices etc…more ingredients, more complex ingredients, harder to acquire ingredients for the higher end recipes. The cooking skill required would naturally go up as the harder recipes are used. And the fishing skill required would also go up in order to use the higher end fish food & chum.
The item cooked/created would allow you to cast/throw that item out onto the water, creating your own fishing pool. The pool created would be dependant upon the zone it was used on; common/low level food creating a pool that naturally occurs in that zone. Higher end recipes with the complex food & chum would create a rare fish pool, giving us anglers a unique fishing pool for a totally different fishing experience!
