why is ludens so bad....
simply put its kept on a lowish power budget because MS is a powerful stat. which i get. but as it stands now the item is never bought solely because of its price. you build a large rod, you back with a lot of gold, you see you can buy AA, ludens, or rylais, now of the 3 which would you pick....
rylais every time. it simply gives better combat stats or utility. the MS on ludens isn't chosen nearly as often as is the health or slow.
ludens simply activates too infrequently to be seen as anything other than 100ap 10%ms, rylais is just all around more effective in terms of combat stats its better to remove 40% from the enemy than buff yourself by 10%.
so in my opinion theres only 3 options.
1 is to lower the cost of the item. 2 is to increase the raw ap the item gives 3 is to change the active into more single target burst or activate more often.
whichever is deemed appropriate.
in my opinion i would lean towards option number 2 as people should be building ludens for better damage dealing capabilities, but that also raises the concern of the effect just not being strong enough so it is a toss up overall.
i would even be ok with a higher cost so long as it gave even more ap and would do its job in terms of damage output.
edit - included cost analysis.
Gold Value 100 ability power = 2175 Gold 10% movement speed = 395 Gold Total Gold Value = 2570 Gold
Gold Efficiency Luden's Echo item.png Luden's Echo is 80.31% gold efficient, without ECHO. For the item to be gold efficient, its passive must be worth at least 630 Gold
They have all kind of fallen out of favor for now, especially the first two. Pure damage just isn't good enough right now unless you either have some insane defensive cool down or huge range.
