No in my opinion. What you basically suggesting is similar what we have in waves, only 8 slots and a bunch of morale points that cannot be used in any way or can be used only for 3 big monsters. The same would happen with towers. I don’t want to have in my defense either 30 crap towers, or either 15 good ones (that I’ve been upgrading for 2 years I’m playing the game). . I want to have 20 maxed out, strongest towers I’ve been working for so such a long time. If your suggestion would allow me to still have them, others would have to have the possibility to put 40-60 crap towers with less points you suggesting, I don’t see this happening to be honest.
Balancing towers you put at your base already happened with those boosts we have. LTs wouldn’t be used at top levels if they weren’t boosted. Arrow towers can still be useful with boost to a certain level (not at the top but it is ok in my opinion, it is logical). Gargs also would be useless if it weren’t for the boost. Same with barricades. All those towers and obstacles are still used through the whole game to be honest. At top you don’t use only arrow towers and frost towers. Which is quite fair, don’t you think ? We are using everything apart from those two towers.
Also froging made possible to make some useless stuff useful. Look at blockades, they don’t have a boost and they suck compared with boosted barricades but with only a few forges they are already stronger than boosted barricade and if you look closely, blocades are also used by top players.
OliFire, are you claiming knights are not relevant ? They are used through all levels, in offense of course, in defense they don’t matter due to limitation of slots.
