Is he even worth getting if I am not going to upgrade him... at least for a while? I am going to build up songstress. So I was curious is the $5 worth it if I keep him white....
I'm going to be a rebel and say no. Take note I'm a little biased. I'm very frugal when it comes to buying packs and I'm very patient. Actually I regret ever buying Big Guy to Gold!
Here are the reasons:
1) Hero Chapters Tank
Child of Light at Legendary Grade will be a better tank for hero chapters if you can't max out Big Guy. That said you can beat all Elite Chapters without Big Guy.
Big Guy has no place in the colloseum if it isn't Legendary Grade. Even if you have a maxed out Big Guy you don't need him at all actually. He's easily countered by Incinerator. Personally I have more problems beating Child of Light teams.
3) War Hero
Big Guy only got 2 logistic skills. The constuction speed is nice but it isn't hard to max out your buildings. I see that construction boost as "wasted potential". I'd rather invest in heroes that have 3 logistic skills. They are more useful for Attack/Defense. Last but not least when it comes to attacking health > defense so that infantry defense isn't that great. Demon Slayer + Oathkeeper are both better heroes when it comes to attacking.
4) Player EXP Gear
The Exp gear is nice to have, but you can reach Player Level 60 without it. Once you finally reached lvl 60 the exp set becomes useless (until IGG raises the level cap) The Sacred Broadsword is nice early on, but Fiery Tomahawk is better and you can craft it for free
TL;DR Big Guy is good but only if you go all the way. Even then if you have patience and value your money I'd suggest investing in something else. Getting Big Guy to Gold costs 276usd wich is equal to 55x 5usd packs! You can get 2 P2P heroes to Legendary Grade if you keep buying the 5usd packs and play long-term.
Saving time and increasing efficiency is the name of the game. Big guy helps you because of all the speed ups, bravehearts and the gear. It helps a lot of you got the big guy set early into the game for the legendary construction bonus, exp gear and RSS stuff. The big guys is one of the only packs that you benefit more if you get it earlier in the game!!
Big guy is a great hero that can help you early on. Getting level 60 as soon as possible is a huge advantage especially in colosseum and in war time due to talents... This can make you earn gems faster and become stronger at a faster rate. RSS production helps so that you don't have to use so many RSS packs in the game. This may not feel like much but if you play the game for so long, it does start to add up.
Getting it early to gold actually save months of progress which is critical!
