So this has been bothering me for a while, but why do some items lose stats and/or abilities when they are upgraded? A great example of this is 
Everything that builds with this, loses the passive gold gain and the bonus gold gain from killing things. Why have this be part of an item if it loses all it's bonuses once you upgrade?
khorney2 voteswell the best way to do this is get avarice blade asap and sit on it or farm it so to speak
ZephyrDrake1 votesdo you want 
and 
to be weaker or more expensive just to accommodate for the gold regen stats?
UberAffe1 votesOr remove the gold gen and make avarice more useful.
only zhule1 votesthat could work, also fine with them just removing the item up the cost of the combine by 400 (cost of upgrading from the crit glove thing to blade) and BOOM no difference.
Would also except a new item that is based around the gold generation
DrNova1 votesYeah avirice is stupid. You either build into it for a tiny amount of time, or build past it altogether.
aaronautumn1 votesit's a relic of a time when all gp10 passives were lost on upgrade. (HoG>Randuins, Lucky Pick>Item-whose-name-I've-forgotten, Philo>Support items, etc) they might not want to add a new crit item to replace it.
LaoBushido1 votesi think you picked a bad example for this point, in this case avarice blade grants bonus gold per kill there are many champs like most adc or 
that rush or if the passive transferred it would allow the buyer in most cases to get very far ahead. riot want to make it so that gold is a scare , that why 
has a decent cool down on his q and the support item have 
have time restrictions on them. the only exception i can think of on the gold point is 
but his gold gain is randomized and it take a lot of gold for him to be effective late and mid game
Decrit1 votesConceptually is because that gold gained should help you to get the next item, and not to keep generating gold.
This was a thing common in the previous seasons, there were other items like that ( Philosopher' s stone, Heart of gold and Kage lucky pick, now spellthief' s edge ) and only the shard of true ice mantained a gold generating passive at the final stage, because in fact it was conceived to be a support item ( that item got changed in Frost Queen' s Claim )

Oh i rememeber the items. I remember a time where i would sometimes see a support rocking 4 gold items in the mid game so that if the game ran another 10 mins they would have the gold needed to build their end game stuff.
Decrit1 votes4 gold items? really? with Leona i picked up only HoG and PStone, then i had to dump the rest of my gold on wards, elixir and maybe a pair of boots...
i am glad s3 came :P
