I certainly hope you are wrong about decal being "dead" and if you are not, than I hope that Elgar can make Eltank work without decal.
I have been playing for four years and have used decal/eltank the last two or so. I use eltank to search for things, to navigate around Dereth, I use it to self buff (and buff others who might be in need), I use it to track my quests timers, I use it to communicate on more than one channel (bringing all the community closer to me), I use it to tell me how much a critter is when I kill it (pops right there for me), I track my comps and many other things, too numerous to mention.
All in all, Eltank/decal has kept me playing this game for the last couple of years. I never self buffed before tank, I found the spellbar to be encumbersome and tedious, trying to remember "what spell I last cast and which should be next", time consuming and certainly took away from the "fun" of playing.
These TPA's have ENHANCED my AC game time and game play. I don't UCM, I don't ACM... but I do like to use my time efficiently. I don't like doing repetitive tasks that bore you to tears, I want to have FUN. That's why I play an online computer game.
If I don't have these enhancements, I can see AC becoming just too tedious to even enjoy.
You can't unring a bell that has rung! You can't go backwards ... you can only move forward. AC won't ever be what it "used to be". There are not "good old days".. THESE are our good old days!
I hope that decal and Eltank live as long as AC itself. They make a great TEAM!
