In the Skill hall u can build a rune case 1 with 2 teak planks, 2 molten glass, 1 air rune, 1 fire rune, 1 water rune and 1 water rune (lvl 14 rc required). The construction xp for that is 190 xp (normal for 2 teak planks is 180 xp). In the Knowledge Database is stated:

 

You receive the same amount of Runecraft experience to that of the Construction values below when you make a rune case.

 

 

So for those 2 molten glass and 4 elemental runes u get 10 extra construction xp and 190 rc xp, which is more xp than u can get when using that glass for crafting. So i decided i would train construction with that. After 60 cases I realized i should have leveled up rc but didn't. Then found out the rc xp was only 25 for each case.... And that's not worth the trouble.

Yeah, they changed the xp from the armor stands from 135 to 25 smithing xp too. It used to be great xp for smithing along with construction since you kept the armor and could keep rebuilding.

Thx for mentioning that, cause I used to train with armour a lot and was planning to go back to armour. Just checked it. Building mith armour (all I can manage) now gives me 135 construction xp and 25 smithing xp. So the bonus of 15 construction xp survived (2 oak planks normally give 120 xp). I think the armour is still worth the trouble if u dont want to spend a lot of gp on construction. U can leave the armour on the stand, so it doesn't take extra inventory space like the rune case. Although u need to build other items first, so u get 3 spaces in ur invent free for removing the armour. A tip: dont wear anything when u train with armour. When u makte the mistake of removing the armour without having 2 oak planks in ur invent, u can wear the armour to free invent space.

It was reasonable to nerf the xp for smithing. As many would advance construction with oak planks anyway, it was slower but better xp all around. Even at 25 xp for smithing, I may consider it.

 

 

 

For the RC, well, I don't see the need to nerf this. The cost to make the cast (2 molten glass, 2 teak planks, 4 element runes) is much higher than getting the xp at the Law World. However, this way people would raise xp in RC without putting runes into the economy. It would keep the market for mass teaks into play.

 

 

 

Of course, once nerfed, xp is rarely returned to its former state. We can only rant about it.
