Well even though as it was stated it is not going to get changed i would just give a few of my thoughts.
(From ranger perspective!)
- So i invested all my points in spot. I also have some decent spot gear. Not the best, but not the worst neither. (got even 1 hector ring!). However if i compare my character to a same level cleric or druid. They negate and surpass the invested skill points easily. Even if they have only merely half the points(if they bother to invest in spot), they easily make up for it just via spells or feats. Empowered/maximised owls wis, owls insight...prayer (And let us face it most of the time you will have a hard time finding someone willing to cast the spot/listen enhancing spells on your characters.) And druid with their new feats....if they stack then it is a flat 12 spot bonus. Also in comparision to my previous sneaker char of nearly the same level, who was not such a dedicated sneaker since he did NOT take up the sneak feats, i would still not notice him. Simply because his sneak gear outweighs the spot gear so badly. (Especially now with a few new potions and items he would be an even better sneaker, had in 2011 on level 14 62/60 sneak)
-Spot does not earn you any gold, whereas ninjalooting does. Spot though can earn you some minor xp, or search not sure.(You may have a hidden check of one of the mentioned two skills for some minor xp in certain areas.) But so can sneak both directly and indirectly.(direct: successfull near fail sneak check, certain areas where you can get different mobs kill off each other and give you a bounty with good xp , indirect: items obtained through sneak allows you more possibilities)
-I am unsure if i know all the spot items in game, but as per my calculations a dedicated sneaker who is maxed out on sneak is somewhere around 105+ to a max of maybe 120? (race and other modifiers). Whereas if i calculated well currently spot will cap around 82(?) or so. (with this 82 did not take into consideration the druid feats!, but multiple classes using spot enhancing magic and feats like bard song on you.)
-Regarding the spot items vs the sneak items, I have yet to see a single item (beside the telescope i think) that is a handheld item and gives bonus to spot. Whereas the +1/+1 +2/+2 +3/+3 +4/+4 sneak items are NOT that uncommon.(Also interestingly enough all these sneak items are weapons, for instance a bow is quite a good choice for a higher level sneak ranger with bane bow or hawk's)
-Regarding potions there is currently owls wisdom, TS and the keen senses potions if i know well. On the other hand we have chameleon, 1wthland and tiptoe and cats grace.
-Another issue with spot vs stealth is, that the spot classes, if they employ their spot gears, will be terribly at a disadvantage.
Lower AC, lower Saves, lower everything. For a sneaker it is not necessarily so, since well they can use powerfull magic. Especially since PM and Bards are both sneak chars.
(Is also funny how tiptoe/light step is not a ranger spell, but that is a different concern or topic)
- Shrouded Dance in this regard can be considered quite OP as well, since if you spot someone needing a 20 to spot him, just one button push and he or she is gone again, and depending on the pseudo random generator well you may never notice him or her again.
- Currently as i see it spot has more disadvantages than advantages regarding sneaks. If i would have not amassed the spot gear on this char originally i would have switched over to listen during my remake. //As i heard though not sure about this, that having a higher listen also extends the range from where you can hear whispers. //
